Can you rename the libraries? Or maybe change the config script to
generate the proper names? (I don't know - it's been too long since I
used cygwin - and then not with PHP).

I doubt you'll get any help. Is there a version of PHP in the cygwin
libraries (I don't know - it's been too long since I used cygwin, but
IIRC there was one)? Maybe that will help get you on the right track.

Yup, XP is at EOL and pretty soon there won't be any further updates. I
know it's a hassle - I still have a couple of programs which don't run
under Windows 7 (even in emulation mode) so I have to use a Windows XP
virtual box. A hassle.
And yes, cygwin is more lightweight; if the overhead of a virtual box is
a problem for you, than that's the way to go.
Of course, you can get some pretty cheap laptops nowadays. Maybe it
would be worth investing in one and just installing Linux on it :)
Or if you don't need to move around, desktops are getting even cheaper :))
