CVS gettext had a compilation warning due to a missing value for CHARCLASS_NAME_MAX. Cygwin regex currently only supports char-class names of up to 6 characters (for example, "[:xdigit:]"), but POSIX requires a minimum of 14 when locales are free to define their own char-class names. While I was at it, I noticed that several of the limits.h constants that are required to be the same across all platforms were missing or incorrect. And we might as well publicize our limit for declaring ELOOP on symlink chains, rather than keeping it hidden in path.h. 2006-04-15 Eric Blake <ebb9@byu.net> * include/limits.h (_POSIX_*, _POSIX2_*, _XOPEN_*): Define missing standard constants, and correct invalid ones. (CHARCLASS_NAME_MAX): Define. (SYMLOOP_MAX): Define. * path.h (MAX_LINK_DEPTH): Define in terms of SYMLOOP_MAX. * regex/regcomp.c (p_b_cclass): Limit length of char class name.
