I'm not going to get into this issue now.

I intend to add as little special stuff for Cygwin as possible.

In a day or so I should have something that you can try.

So you'll be able to tell me how to do it?

The sort of changes I've made so far to build Win32:: under cygwin fall 
into the following groups:

i) Extended the mechanism in the libwin32 top level Makefile.pl which
enables excluding the building of Win32:: sub packages depending on $^O.

ii) Added conditionals to c source to stop WIN32 from leaking out of 
cygwin's w32api/windows.h into source that wants to see __CYGWIN__ and
not WIN32. There are some other bits and pieces of this nature.

iii) Spilt perl-5.6.1/win32/win32.[ch] into 2 parts, the Win32 runtime - 
Perl glue and the routines that provide the core Win32:: functionallity 
ie Win32::GetLastError. Conditionally compile and link Win32core.c against
Win32.c of libwin32-0.18. This makes Win32:: behave as just another 
package under cygwin, rather than being builtin as it is on Win32/Perl.

iv) Added LDLOADLIBS and MYEXTLIB settings to the Makefile in various 
Win32:: sub packages, this needs to be done conditioned on $^O eq 'cygwin' 
via Makefile.pl, but I've not worked out how to do this with 5.6.1 Makemaker 
yet. ???
