-
-   Note that it is safe to write "void foo();" indicating a function
-   with no return value, in all K+R compilers we have been able to test.
-
-   For declaring functions with prototypes, we also provide these:
-
-   PARAMS ((prototype))
-   -- for functions which take a fixed number of arguments.  Use this
-   when declaring the function.  When defining the function, write a
-   K+R style argument list.  For example:
-
-	char *strcpy PARAMS ((char *dest, char *source));
-	...
-	char *
-	strcpy (dest, source)
-	     char *dest;
-	     char *source;
-	{ ... }
-
-
-   VPARAMS ((prototype, ...))
-   -- for functions which take a variable number of arguments.  Use
-   PARAMS to declare the function, VPARAMS to define it.  For example:
-
-	int printf PARAMS ((const char *format, ...));
-	...
-	int
-	printf VPARAMS ((const char *format, ...))
-	{
-	   ...
-	}
-
-   For writing functions which take variable numbers of arguments, we
-   also provide the VA_OPEN, VA_CLOSE, and VA_FIXEDARG macros.  These
-   hide the differences between K+R <varargs.h> and C89 <stdarg.h> more
-   thoroughly than the simple VA_START() macro mentioned above.
-
-   VA_OPEN and VA_CLOSE are used *instead of* va_start and va_end.
-   Immediately after VA_OPEN, put a sequence of VA_FIXEDARG calls
-   corresponding to the list of fixed arguments.  Then use va_arg
-   normally to get the variable arguments, or pass your va_list object
-   around.  You do not declare the va_list yourself; VA_OPEN does it
-   for you.
-
-   Here is a complete example:
-
-	int
-	printf VPARAMS ((const char *format, ...))
-	{
-	   int result;
-
-	   VA_OPEN (ap, format);
-	   VA_FIXEDARG (ap, const char *, format);
-
-	   result = vfprintf (stdout, format, ap);
-	   VA_CLOSE (ap);
-
-	   return result;
-	}
-
-
-   You can declare variables either before or after the VA_OPEN,
-   VA_FIXEDARG sequence.  Also, VA_OPEN and VA_CLOSE are the beginning
-   and end of a block.  They must appear at the same nesting level,
-   and any variables declared after VA_OPEN go out of scope at
-   VA_CLOSE.  Unfortunately, with a K+R compiler, that includes the
-   argument list.  You can have multiple instances of VA_OPEN/VA_CLOSE
-   pairs in a single function in case you need to traverse the
-   argument list more than once.
 
    For ease of writing code which uses GCC extensions but needs to be
    portable to other compilers, we provide the GCC_VERSION macro that
    simplifies testing __GNUC__ and __GNUC_MINOR__ together, and various
    wrappers around __attribute__.  Also, __extension__ will be #defined
-   to nothing if it doesn't work.  See below.
-
-   This header also defines a lot of obsolete macros:
-   CONST, VOLATILE, SIGNED, PROTO, EXFUN, DEFUN, DEFUN_VOID,
-   AND, DOTS, NOARGS.  Don't use them.  */

+   macros which can be redefined by the including file.
+   
+   The macros are in sections.  Each section corresponds to a single
+   set of DWARF constants and has a corresponding key.  The key is
+   used in all the macro names.
+   
+   The sections are TAG (for DW_TAG_ constants), FORM (DW_FORM_), AT
+   (DW_AT_), OP (DW_OP_), ATE (DW_ATE_), and CFA (DW_CFA_).
+   
+   Using TAG as an example, the following macros may be used for each
+   key:
+   
+   DW_FIRST_TAG(name, value) - Introduce the first DW_TAG constant.
+   
+   DW_TAG(name, value) - Define a subsequent constant.
+   
+   DW_TAG_DUP(name, value) - Define a subsequent constant whose value
+   is a duplicate of some other constant.  Not all keys use the _DUP
+   macro form.  If more than one name shares a value, then the base
+   (DW_TAG) form will be the preferred name and DW_TAG_DUP will hold
+   any alternate names.
+   
+   DW_END_TAG - Invoked at the end of the DW_TAG constants.  */

+
+   1) umul_ppmm(high_prod, low_prod, multiplier, multiplicand) multiplies two
+   UWtype integers MULTIPLIER and MULTIPLICAND, and generates a two UWtype
+   word product in HIGH_PROD and LOW_PROD.
+
+   2) __umulsidi3(a,b) multiplies two UWtype integers A and B, and returns a
+   UDWtype product.  This is just a variant of umul_ppmm.
+
+   3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator) divides a UDWtype, composed by the UWtype integers
+   HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and places the quotient
+   in QUOTIENT and the remainder in REMAINDER.  HIGH_NUMERATOR must be less
+   than DENOMINATOR for correct operation.  If, in addition, the most
+   significant bit of DENOMINATOR must be 1, then the pre-processor symbol
+   UDIV_NEEDS_NORMALIZATION is defined to 1.
+
+   4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
+   denominator).  Like udiv_qrnnd but the numbers are signed.  The quotient
+   is rounded towards 0.
+
+   5) count_leading_zeros(count, x) counts the number of zero-bits from the
+   msb to the first nonzero bit in the UWtype X.  This is the number of
+   steps X needs to be shifted left to set the msb.  Undefined for X == 0,
+   unless the symbol COUNT_LEADING_ZEROS_0 is defined to some value.
+
+   6) count_trailing_zeros(count, x) like count_leading_zeros, but counts
+   from the least significant end.
+
+   7) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
+   high_addend_2, low_addend_2) adds two UWtype integers, composed by
+   HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and LOW_ADDEND_2
+   respectively.  The result is placed in HIGH_SUM and LOW_SUM.  Overflow
+   (i.e. carry out) is not stored anywhere, and is lost.
+
+   8) sub_ddmmss(high_difference, low_difference, high_minuend, low_minuend,
+   high_subtrahend, low_subtrahend) subtracts two two-word UWtype integers,
+   composed by HIGH_MINUEND_1 and LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and
+   LOW_SUBTRAHEND_2 respectively.  The result is placed in HIGH_DIFFERENCE
+   and LOW_DIFFERENCE.  Overflow (i.e. carry out) is not stored anywhere,
+   and is lost.
+
+   If any of these macros are left undefined for a particular CPU,
