In file included from ./unistd.h:135:
In file included from ./getopt_pfx_core.h:52:
./getopt_core.h:91:79: error: expected ';' after top level declarator
extern int getopt (int ___argc, char *const *___argv, const char *__shortopts)
Can you please send the preprocessor output for the failed compilation?
That is, try running "make V=1". If the failed command looks like this:
clang -c -Dthis -Dthat -Dtheother fstatat.c
then run this command:
clang -E -Dthis -Dthat -Dtheother fstatat.c >fstatat.i
and send a copy of fstatat.i as an attachment.
Also, can you find out which .h file defined __THROW and __nonnull in your environment? I have the sneaking suspicion that it's some .h file other than getopt_cdefs.h.
Thanks.
