include:
* safe-ctype.h: New file.
libiberty:
* safe-ctype.c: New file.
* Makefile.in (CFILES): Add safe-ctype.c.
(REQUIRED_OFILES): Add safe-ctype.o.
* argv.c: Define ISBLANK and use it, not isspace.
* basename.c, cplus-dem.c, fnmatch.c, pexecute.c, strtod.c,
strtol.c, strtoul.c: Include safe-ctype.h, not ctype.h. Use
uppercase ctype macros. Don't test ISUPPER(c)/ISLOWER(c)
before calling TOLOWER(c)/TOUPPER(c).
gcc:
* Makefile.in (HOST_RTL): Add safe-ctype.o.
(safe-ctype.o): New rule.
* system.h: Include safe-ctype.h, not ctype.h. No need to
wrap ctype macros.
* cpphash.h: Zap IStable and related macros. Define is_* in
terms of safe-ctype.h macros.
* cppinit.c: Delete the IStable and all related code.
* tradcpp.c: Delete is_idchar, is_idstart, is_hor_space, and
is_space arrays. Delete initialize_char_syntax. Change all
references to the above arrays to use macros instead.
* tradcpp.h: Define is_idchar, is_idstart, is_space, and
is_nvspace in terms of safe_ctype.h's macros.
* tradcif.y: is_idchar, is_idstart are macros not arrays.
* config/i370/i370.c, config/winnt/dirent.c,
config/winnt/fixinc-nt.c, config/winnt/ld.c:
Use uppercase ctype macros. If we included ctype.h,
include safe-ctype.h instead.
* fixinc/fixfixes.c: Use uppercase ctype macros. Don't test
ISLOWER(c) before calling TOUPPER(c).
* fixinc/fixincl.c (extract_quoted_files): Simplify out some gunk.
* fixinc/gnu-regex.c: Include safe-ctype.h, not ctype.h. No need to
wrap ctype macros. Don't test ISUPPER(x) before calling TOLOWER(x).
gcc/ch:
* lex.c: Don't bother checking whether ISUPPER(c) before
calling TOLOWER(c). Don't bother checking whether isascii(c)
before testing ISSPACE(c); ISSPACE(c) includes '\n'.
gcc/f:
* Make-lang.in: Link f/fini with safe-ctype.o.
* bad.c: Don't test ISUPPER(c) || ISLOWER(c) before calling TOUPPER(c).
* com.c: Use TOUPPER, not ffesrc_toupper.
* fini.c: Don't test ISALPHA(c) before calling TOUPPER(c)/TOLOWER(c).
* intrin.c: Don't test IN_CTYPE_DOMAIN(c).
* src.c: Delete ffesrc_toupper_ and ffesrc_tolower_ and their
initializing code; use TOUPPER and TOLOWER instead of
ffesrc_toupper and ffesrc_tolower.
* src.h: Don't declare ffesrc_toupper_ or ffesrc_tolower_.
Don't define ffesrc_toupper or ffesrc_tolower.
gcc/java:
* jvgenmain.c: Use ISPRINT not isascii.
