I think this would make more sense if the gnulib md5 module used the BSD
API and thus would be a fallback for systems without these functions,
just like the getopt module is a fallback for systems without
getopt_long() and friends.
Because the md5 module uses a different API, a different header name
would be more obvious, for example gmd5.h.

As it is now, once you imported the gnulib md5 module, you cannot access
the BSD API anymore (if you don't want to make local changes to gnulib
modules). For this reason I will probably just stop using the BSD
functions and always use the gnulib module, as suggested by Simon.
