Help: Kaffe HelloWorld doesn't run on Cygwin32

[Buick, Robert]

Hi,
I've got kaffe to build on NT 4.0 but get an assertion similar to
2443.html 'Re: Porting 1.0.b1 to hpux 10.10', namely: 
FIOASYNC: Invalid argument
assertion "mainthread" failed: file
"./systems/unix-jthreads/internal.c", line 114.
It runs to jthread.c:jthreadedFileDescriptor.line 1512 ie
r=ioctl(fd,FIOASYNC,&on) where it returns -1. This eventually causes its
calling mainthread to assert (internal.c:Tinit().line 114

commenting this out or running without debug produces:
