Yep - a gnulib problem. Unfortunately, gzip 1.3.13 postdates commit 35cea22, where I already tackled the same issue for glibc. This is a sign that our #include_next of darwin's <getopt.h> worked, but that darwin's header recursively includes some other header that calls back to our <getopt.h>, prior to the completion of the first use of the system's <getopt.h>. It is generally fixable by teaching gnulib what preprocessor guards darwin was using during that recursion, but I'll need to see the darwin getopt.h before I can prepare a fix. gcc -E output might be helpful as well, as it would pinpoint what files are involved in the loop. I think I can get access to a darwin machine later today to try and reproduce/fix the issue. -- Eric Blake
