problems with cygwin.dll



Well I applied gdb to my problem and got the following results.  As
you can see from the stack trace the interpreter is calling my native
functions fine but seg faults inside of printf.  Could it be that the
fact that the interpreter uses all these MS libraries prevents me from
using cygwin.dll?  Could I possibly get around this by statically
linking the symbols I need from cygwin.dll into my dll (its the one
called ra200.dll)?  Does that even make sense?

I think being able to use gnu-win32 for Java native libs would be a
big win and if I can get past this and figure out whats going on I'd
be happy to contribute a HOWTO as far as how to do this.

I'd appreciate it greatly if anyone could help me on this one.
