this returns *not* 1 with musl. according to Rich the commented
behaviour is a gnuism and not POSIX.
I've run into the same issue. Attached is the patch I use to work around
it.
the unzip applet may be a candidate for custom argv parsing code, getopt
doesn't seem to be a good fit in this case,
especially considering Doug Clapp's report (apparently not even on glibc
all options behave as they should).
but then, i've never gotten around to study the getopt manpage, so there
may be some trick to make it work in a POSIX conformant fashion.
