ctype, string: depend on extern-inline This is needed to complete the recent OS X fixes. Also, fix related documentation as suggested by Eric Blake. * doc/posix-functions/isalnum.texi, doc/posix-functions/isalpha.texi: * doc/posix-functions/isascii.texi, doc/posix-functions/iscntrl.texi: * doc/posix-functions/isdigit.texi, doc/posix-functions/isgraph.texi: * doc/posix-functions/islower.texi, doc/posix-functions/isprint.texi: * doc/posix-functions/ispunct.texi, doc/posix-functions/isspace.texi: * doc/posix-functions/isupper.texi, doc/posix-functions/isxdigit.texi: * doc/posix-functions/toascii.texi, doc/posix-functions/tolower.texi: * doc/posix-functions/toupper.texi: List the 'ctype' gnulib module. * doc/posix-functions/strcat.texi, doc/posix-functions/strcpy.texi: * doc/posix-functions/strncpy.texi: List the 'string' gnulib module. * modules/memcpy, modules/memmove, modules/memset (Depends-on): Add string. * modules/ctype, modules/string (Depends-on): Add extern-inline.

Gnulib module: ctype
Portability problems fixed by Gnulib:
@itemize
@item
This function cannot be called from plain inline or extern inline functions
on some platforms:
OS X 10.8.
@end itemize
Portability problems not fixed by Gnulib:
@itemize
@end itemize
Note: This function's behaviour depends on the locale, but requires special
handling for the multibyte characters that occur in strings in locales with
@code{MB_CUR_MAX > 1} (this includes all the common UTF-8 locales).
There are two alternative APIs:
@table @code
@item c_isascii
This function operates in a locale independent way and returns true only for
ASCII characters. It is provided by the Gnulib module @samp{c-ctype}.
@item mb_isascii
This function operates in a locale dependent way, on multibyte characters.
It is provided by the Gnulib module @samp{mbchar}.
