Exactly.
what do you think?
I fully agree with your analysis. But I'm afraid the glibc people will
argue that their implementation is posix conform and that there are
(glibc-only) workarounds for our problem available.
So I think the best way to circumvent this is to further clean
up the getopt.c I've posted and to include it in gengetopt.
I've just posted a tentative version that uses the customized version to
solve the problem
actually, as far as I understand, the posix says that at the beginning
optind must be 1, so it makes sense (at least to me :-) that optind = 1
must be considered the initialization condition and not optind = 0
This not only avoids future compatiblility issues with other
implementations of getopt, but also gives us the freedom to change
things at will rather than having to rely on a standard which simply
doesn't cover things like multiple parsers or a non-constant argv.
yes but my only concern is that any future updates/addition to getopt
implementation must be adapted by hand to the customized version...
time will tell ;-)
hope to hear from you soon
cheers
