You wonder how people stayed sane before pkg-config!

I checked in the test program:

http://hg.savannah.gnu.org/hgweb/mingw-cross-env/rev/d94200f96aa7

Then went through a few iterations to come up with a build that succeeds:

http://hg.savannah.gnu.org/hgweb/mingw-cross-env/rev/deab4460f78d

With the ordering of included libs, we should be able to come up with
a *.pc file that makes this easy.

Please test and report your findings.

Cheers,

Tony
