I will try as soon as I can reboot into Windows 2000 SP4.

Yes I am running cygwin-1.5.9-1 on Win2000 and do not have the cygwin
snapshot. I will try the snapshot maybe tomorrow night.

Only because it seems that gcc -v on most/all linux distributions show
this, maybe it is automatic even if you don't ask for it---need to test
that.  I.e., I don't know, I assumed it was the normal choice.

A vendor supplied cross-compiler, gcc -v shows them using these settings
and I just made the same choices (to be compatible).  This vendor's
compiler also show the posix threads selection.

I try to find time to extract the C test program and see if it crashes,
if the latest cygwin snapshot fails to fix it.

Thanks very much for your suggestions,
