I knew I should have mentioned this in the first message. But, yes I
know. The problem is, it never even gets to that section. That
message is never displayed on the screen so it seems the thread is
never called.
I just compiled and ran it in insight (gdb gui) and something
interesting is showing. The pthread_create causes a seg fault and
the debugger cuts to assembly of cygwin1... Can someone try that
code below, and tell me if it runs?... maybe it is my cygwin that is
screwy (shouldn't be, I just d/l it two days ago, clean install)
