trying again - cpan/gcc cannot compile perl module after cygwin1.5*

[Brian dot Kelly at Empireblue dot com]

Before the upgrade to 1.5* - 64 bit cygwin, this used to compile with the
default configuration just fine. Now it can't. I am aware that the entire
perl libwin32-0.191 distribution never did work completely with cygwin -
especially named pipes. However, the Win32::Semaphore module *did* - and
before the 1.5* upgrade, compiled flawlessly with the default
configuration. Not only that, but the resulting Win32::Semaphore.pm
*worked* flawlessly as well - and is an integral part of a production
system I now maintain. Luckily, the compiled binary from the previous
version of cygwin/gcc combo works just as flawlessly with the current
64-bit release of cygwin - but I can no longer compile it with the default
installation. I have backups of the binary - so there are no real problems
currently. However, since I can't and don't want to roll-back cygwin, I
need to find a way to successfully compile it with the latest version of
cygwin/gcc. If someone can see a quick fix - or work around - to this it
would obviously be a BIG help and be much appreciated.

Of course I'm aware that cygwin is now *64* bit compiled, and that I'm
looking to compile a *32* bit module. So I guess my first question, is
there backward compatibilty? And, if there is, how can I invoke it for
successful compilation? Also - any hope that the default installation will
ever again compile this, or is there now a need for a Win64::Semaphore
module?
