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.

This patch is not covered under the trivial patch rule anymore.
