Subject: Re: Building Windows C Extension

Building an extension on Windows can be an exercise in frustration.
The biggest problem is that Windows Ruby is still built with VC6 and
thus extensions built with any later technology probably won't work.

The best way I've done it is through Cygwin. There are ways of getting
mingw to work, but it's not pretty and not guarenteed. With the
One-Click Installer, try the following:

CPPFLAGS=-D_MSC_VER=1200 LIBS=-lmsvcp60 ./configure

then see if the compilation will work for you.
