Subject:	Win32::API perl module

I have been trying to compile up Win32::API perl module under Cygwin's 
perl.

The latest version off CPAN doesn't build (see below).

I have found some refernces to patches people have applied to get it 
working in the past.  In particular Win32:API version 0.20.
    http://anfaenger.de/cygwin/libwin32/Win32-API-0.20cygwin/
But I was unable to get that working either, maybe because the 
Cygwin.dll and/or Perl (v5.8.2) has moved on since that patch was done?

I was wondering if anyone has got it working for themselves?
If not, I'd really appreciate someone taking a look. I am happy to do 
some of my own dirty work, but I have little knowledge of the Cygwin.dll 
so I really struggle to know where to look. I gather Win32::API is 
relying on a hook that the Cygwin.dll is not providing?

All I really need this for is to call a procedure in a DLL, that does 
some port IO for me. At the moment my work around is to use Active State 
perl, for which Win32::API does build, but it would be better to only 
have one version of Perl around.

Regards,
Jason
