Thanks William, it is very useful.

The configure script checks if getc_unlocked() and flockfile()
exist. If I've done it correctly, HAS_STDIO_UNLOCK should only
be set to 1 if they do. Can you please tell send me the output
of configure, and some examples of the error messages you get?
It feels like a MinGW bug, but I don't have it to test. If
necessary, a MinGW exception can be made in configure.

Yes, good idea. I'll do that.

That's a bug, it should be
#ifdef CPUDEFS
CPUDEFS
#endif
Cheers, Brendan.
