getting cmd line options

Is the getopt.c file from GNU a fully portable C source file
to use even in a platform that it's not in its std C lib ( e.g. UNIX )?

If not could you suggest a platform independent getopt.c
file ?

Sorry, for not having the time to test it myself...

There's some details here

well, it's a good FAQ
but i didn't find my answer there.

I managed to compile GNU getopt.c file with minor
modifications.

thanks anyway
