Your absolutly right. It seems that configure screws up something. After
replacing

    updir:= $(dir $(srcdir))

with

    updir:= ../

within winsup/Makefile manualy the whole packages builds cleanly.

Now I'm ready to go ahead in trying to get pthreads running. Geoffrey mentioned
that the latest winsup snapshot supports a configure options caleld
--enablethreadsafe to support at least experimental thread support.

Will this include and build the pthread package or will I have to compile it from
the pthread-win32 package available at sourceware.cygnus.com?

The latest pthreads-snap-1999-01-23 claims within README to be unable to compile
under Cygwin or Mingw. I have compiled successfully the older
pthreads-snap-10-20, but when linking the example programs I get undefined
references to _beginthreadex and _endthreadex, which obviously are not supported
on Win9x systems.

May you have a clue how to get basic pthread support for Cygwin, if possible?

Thanks for assistance.

What do you mean with an object directory? In other words: Where is the
difference in a source and object directory within this scope?

Regards,
Stipe
