d646513e57 getopt_long(3): note an inconsistency with getopt(3) in BUGS 
getopt_long(3) will not allow an `optind` setting of 0 to be bug-for-bug
compatible with the GNU implementation, as some software does rely on
it.  Document it as a BUG, since it affects previous declarations of
compatibility with getopt(3).

3b89018938 getopt_long(3): Document behavior of leading characters in optstring 
Leading '+', '-', and ':' in optstring have special meaning. We briefly
mention that the first two have special meaning in that we say
POSIXLY_CORRECT turns them off, but we don't actually document their
meaning. Add a paragraph to RETURN VALUES explaining how they control
the treatment of non-option arguments.

A leading ':' has no mention; add a note that it suppresses warnings about
missing arguments.

f2fd86b76e Improve GNU compatibility in several places, use internal GNU_COMPATIBLE 
define for it.
Don't catch POSIXLY_CORRECT env. into static variable, it can be changed
on the fly by program.
Use P1003.2 standartized illoptchar[]
