* lib/string.in.h (_GL_STRING_INLINE): Remove macro.
(_GL_MEMEQ_INLINE): New macro.
(memeq): Use it instead of _GL_STRING_INLINE. Test GNULIB_MEMEQ.
(_GL_STREQ_INLINE): New macro.
(streq): Use it instead of _GL_STRING_INLINE. Test GNULIB_STREQ.
* lib/memeq.c: New file.
* lib/streq.c: New file.
* lib/string.c: Remove file.
* m4/memeq.m4: New file, based on m4/stringeq.m4.
* m4/streq.m4: New file, based on m4/stringeq.m4.
* m4/stringeq.m4: Remove file.
* m4/string_h.m4 (gl_STRING_H_REQUIRE_DEFAULTS): Initialize
GNULIB_MEMEQ, GNULIB_STREQ. Don't initialize GNULIB_STRINGEQ.
* modules/string-h (Makefile.am): Substitute GNULIB_MEMEQ, GNULIB_STREQ.
Don't substitute GNULIB_STRINGEQ.
* modules/memeq: New file.
* modules/streq: New file.
* modules/stringeq: Change to just be the union of streq and memeq.
* MODULES.html.sh (func_all_modules): Add memeq, streq.
* m4/stringeq.m4: New file.
* modules/stringeq (Files): Add it.
(configure.ac): Don't set HAVE_DECL_MEMEQ, HAVE_DECL_STREQ. Instead,
invoke gl_FUNC_STREQ and gl_FUNC_MEMEQ.
Work even if the system <string.h> declares memeq and streq.
Current standards allow systems to do that,
and we hope future systems will do it.
* lib/string.in.h (memeq) [HAVE_DECL_MEMEQ]: Do not define.
(streq) [HAVE_DECL_STREQ]: Do not define.
* m4/string_h.m4 (gl_STRING_H_DEFAULTS): Default HAVE_DECL_MEMEQ,
HAVE_DECL_STREQ.
* modules/string-h (string-h):
Substitute HAVE_DECL_MEMEQ, HAVE_DECL_STREQ.
* modules/stringeq (configure.ac):
Define HAVE_DECL_MEMEQ, HAVE_DECL_STREQ.
* MODULES.html.sh (func_all_modules): Add stringeq.
* lib/string.c, modules/stringeq: New files.
* lib/string.in.h: Use _GL_INLINE-related macros.
(memeq, streq): New functions, if stringeq module is in use.
* m4/string_h.m4 (gl_STRING_H_REQUIRE_DEFAULTS):
New var GNULIB_STRINGEQ.
* modules/string-h (string.h): Substitute GNULIB_STRINGEQ.
