I discovered this also.  You also have to avoid librt because it depends 
on libpthread.

My guess is that pthreads is doing some stack and/or heap manipulations 
which are incompatible with those of state threads.


I've also recently discovered problems with my cygwin port of state 
threads.  If I call fork after st_init, cygwin makes a bunch of noise 
about how it couldn't fixup some mmaps or something.  Something to do 
with the assumptions made by the fork implementation when it tries to 
copy all the stack, heap, mmaps and file handles to the new process.

After doing some research I found out that other projects (e.g. python, 
pth) have had similar difficulties in cygwin with their own jmp_buf tricks.
