Having looked at that code myself, I think there's some idiotic tests
going on:
#ifdef __OSNAME
..
#else if __system2__
..
#else if SLOW_BUT_NO_HACKS
//return 1
#else 
//build error
#endif

1. If I define SLOW_BUT_NO_HACKS, it should be the first test.
(if I run MINT and define this, assume I mean it!)
2. If it works with a stub, why do we get an error?

I'd suggest more-or-less this approach:
-#else if SLOW_BUT_NO_HACKS
+#else
//return 1
-#else
-//build error
+//warn "falling back to stub, please port"
#endif

Of course, I know this isn't the right place to discuss such
things--that would be for gnulib.
