That was the same thought I had too. We could do it in Gnulib, since I am not sure how open glibc will be to the idea. I really like when programs support long options, especially for extensions they have beyond POSIX, for example. It would be a shame if Bruno decided to not use getopt_long, because he does not want to deal with this inconsistency arising. I guess he could support them by manually parsing ARGV, but that is no fun. And an easy way to write nasty bugs. :) Collin
