Ah, that's easy to fix then.

The jni_md.h file contains platform-specific stuff, and the name of the
directory it is in varies by platform (though oddly not by architecture
- e.g. it seems to be "linux" for all Linux architectures, whether they
are 32- or 64-bit, despite part of its purpose being to provide typedefs
for jint, jlong, etc).

So we just need to include cygwin in the mapping to "win32" here.

I will backport that to 1.4.x and 1.2.x.

Copying jni_md.h should be fine as a workaround for now.

However, this doesn't seem to explain the messages about "confdefs.h"
- do you still see messages like these having copied jni_md.h over?
