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.
