-dnl Macro to add for using GNU gettext.
-
-dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
-dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
-dnl    default (if it is not specified or empty) is 'no-libtool'.
-dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
-dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
-dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
-dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
-dnl    depending on --{enable,disable}-{shared,static} and on the presence of
-dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
-dnl    $(top_builddir)/intl/libintl.a will be created.
-dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
-dnl    implementations (in libc or libintl) without the ngettext() function
-dnl    will be ignored.  If NEEDSYMBOL is specified and is
-dnl    'need-formatstring-macros', then GNU gettext implementations that don't
-dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
-dnl INTLDIR is used to find the intl libraries.  If empty,
-dnl    the value `$(top_builddir)/intl/' is used.
-dnl
-dnl The result of the configuration is one of three cases:
-dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
-dnl    and used.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 2) GNU gettext has been found in the system's C library.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 3) No internationalization, always use English msgid.
-dnl    Catalog format: none
-dnl    Catalog extension: none
-dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
-dnl The use of .gmo is historical (it was needed to avoid overwriting the
-dnl GNU format catalogs when building on a platform with an X/Open gettext),
-dnl but we keep it in order not to force irrelevant filename changes on the
-dnl maintainers.

-dnl Sets INCLUDE_NEXT and PRAGMA_SYSTEM_HEADER.
-dnl
-dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
-dnl 'include' otherwise.
-dnl
-dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
-dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
-dnl '#pragma GCC system_header' has the same effect as if the file was found
-dnl through the include search path specified with '-isystem' options (as
-dnl opposed to the search path specified with '-I' options). Namely, gcc
-dnl does not warn about some things, and on some systems (Solaris and Interix)
-dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
-dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
-dnl of plain '__STDC__'.

-dnl ------------
-dnl Tests for a multithreading library to be used.
-dnl Defines at most one of the macros USE_POSIX_THREADS, USE_SOLARIS_THREADS,
-dnl USE_PTH_THREADS, USE_WIN32_THREADS
-dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
-dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
-dnl libtool).
-dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
-dnl programs that really need multithread functionality. The difference
-dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
-dnl symbols, typically LIBTHREAD="" whereas LIBMULTITHREAD="-lpthread".
-dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
-dnl multithread-safe programs.

-     with repeated_c.  This reduces the task to testing whether *any of the
-     four* bytes in longword1 is zero.
-
-     We compute tmp =
-       ((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
-     That is, we perform the following operations:
-       1. Subtract repeated_one.
-       2. & ~longword1.
-       3. & a mask consisting of 0x80 in every byte.
-     Consider what happens in each byte:
-       - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
-         and step 3 transforms it into 0x80.  A carry can also be propagated
-         to more significant bytes.
-       - If a byte of longword1 is nonzero, let its lowest 1 bit be at
-         position k (0 <= k <= 7); so the lowest k bits are 0.  After step 1,
-         the byte ends in a single bit of value 0 and k bits of value 1.
-         After step 2, the result is just k bits of value 1: 2^k - 1.  After
-         step 3, the result is 0.  And no carry is produced.
-     So, if longword1 has only non-zero bytes, tmp is zero.
-     Whereas if longword1 has a zero byte, call j the position of the least
-     significant zero byte.  Then the result has a zero at positions 0, ...,
-     j-1 and a 0x80 at position j.  We cannot predict the result at the more
-     significant bytes (positions j+1..3), but it does not matter since we
-     already have a non-zero bit at position 8*j+7.
-
-     So, the test whether any byte in longword1 is zero is equivalent to
-     testing whether tmp is nonzero.  */

-
-   Programs that use <stdbool.h> should be aware of some limitations

-
-   Standards compliance:
-
-       - <stdbool.h> must be #included before 'bool', 'false', 'true'
-         can be used.
-
-       - You cannot assume that sizeof (bool) == 1.
-
-       - Programs should not undefine the macros bool, true, and false,
-         as C99 lists that as an "obsolescent feature".
-
-   Limitations of this substitute, when used in a C89 environment:
-
-       - <stdbool.h> must be #included before the '_Bool' type can be used.
-
-       - You cannot assume that _Bool is a typedef; it might be a macro.
-
-       - Bit-fields of type 'bool' are not supported.  Portable code
-         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
-
-       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
-         performed in such a way that every nonzero value gets converted
-         to 'true', and zero gets converted to 'false'.  This doesn't work
-         with this substitute.  With this substitute, only the values 0 and 1
-         give the expected result when converted to _Bool' or 'bool'.
-
-   Also, it is suggested that programs use 'bool' rather than '_Bool';

-   WINVER symbol before including these two files.  For example,
-   getaddrinfo is only available if _WIN32_WINNT >= 0x0501 (that
-   symbol is set indiriectly through WINVER).  You can set this by
-   adding AC_DEFINE(WINVER, 0x0501) to configure.ac.  Note that your
-   code may not run on older Windows releases then.  My Windows 2000
-   box was not able to run the code, for example.  The situation is
-   slightly confusing because:
-   http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/getaddrinfo_2.asp

-#ifndef VERIFY_H
-# define VERIFY_H 1
-
-/* Each of these macros verifies that its argument R is nonzero.  To
-   be portable, R should be an integer constant expression.  Unlike
-   assert (R), there is no run-time overhead.
-
-   There are two macros, since no single macro can be used in all
-   contexts in C.  verify_true (R) is for scalar contexts, including
-   integer constant expression contexts.  verify (R) is for declaration
-   contexts, e.g., the top level.
-
-   Symbols ending in "__" are private to this header.
-
-   The code below uses several ideas.
-
-   * The first step is ((R) ? 1 : -1).  Given an expression R, of
-     integral or boolean or floating-point type, this yields an
-     expression of integral type, whose value is later verified to be
-     constant and nonnegative.
-
-   * Next this expression W is wrapped in a type
-     struct verify_type__ { unsigned int verify_error_if_negative_size__: W; }.
-     If W is negative, this yields a compile-time error.  No compiler can
-     deal with a bit-field of negative size.
-
-     One might think that an array size check would have the same
-     effect, that is, that the type struct { unsigned int dummy[W]; }
-     would work as well.  However, inside a function, some compilers
-     (such as C++ compilers and GNU C) allow local parameters and
-     variables inside array size expressions.  With these compilers,
-     an array size check would not properly diagnose this misuse of
-     the verify macro:
-
-       void function (int n) { verify (n < 0); }
-
-   * For the verify macro, the struct verify_type__ will need to
-     somehow be embedded into a declaration.  To be portable, this
-     declaration must declare an object, a constant, a function, or a
-     typedef name.  If the declared entity uses the type directly,
-     such as in
-
-       struct dummy {...};
-       typedef struct {...} dummy;
-       extern struct {...} *dummy;
-       extern void dummy (struct {...} *);
-       extern struct {...} *dummy (void);
-
-     two uses of the verify macro would yield colliding declarations
-     if the entity names are not disambiguated.  A workaround is to
-     attach the current line number to the entity name:
-
-       #define GL_CONCAT0(x, y) x##y
-       #define GL_CONCAT(x, y) GL_CONCAT0 (x, y)
-       extern struct {...} * GL_CONCAT(dummy,__LINE__);
-
-     But this has the problem that two invocations of verify from
-     within the same macro would collide, since the __LINE__ value
-     would be the same for both invocations.
-
-     A solution is to use the sizeof operator.  It yields a number,
-     getting rid of the identity of the type.  Declarations like
-
-       extern int dummy [sizeof (struct {...})];
-       extern void dummy (int [sizeof (struct {...})]);
-       extern int (*dummy (void)) [sizeof (struct {...})];
-
-     can be repeated.
-
-   * Should the implementation use a named struct or an unnamed struct?
-     Which of the following alternatives can be used?
-
-       extern int dummy [sizeof (struct {...})];
-       extern int dummy [sizeof (struct verify_type__ {...})];
-       extern void dummy (int [sizeof (struct {...})]);
-       extern void dummy (int [sizeof (struct verify_type__ {...})]);
-       extern int (*dummy (void)) [sizeof (struct {...})];
-       extern int (*dummy (void)) [sizeof (struct verify_type__ {...})];
-
-     In the second and sixth case, the struct type is exported to the
-     outer scope; two such declarations therefore collide.  GCC warns
-     about the first, third, and fourth cases.  So the only remaining
-     possibility is the fifth case:
-
-       extern int (*dummy (void)) [sizeof (struct {...})];
-
-   * This implementation exploits the fact that GCC does not warn about
-     the last declaration mentioned above.  If a future version of GCC
-     introduces a warning for this, the problem could be worked around
-     by using code specialized to GCC, e.g.,:
-
-       #if 4 <= __GNUC__
-       # define verify(R) \
-	   extern int (* verify_function__ (void)) \
-		      [__builtin_constant_p (R) && (R) ? 1 : -1]
-       #endif
-
-   * In C++, any struct definition inside sizeof is invalid.
-     Use a template type to work around the problem.  */

-   Return 1.  */

-# else

-       rest r.
-       The room for q[j] can be allocated at the memory location of r[n+j].
