[Proj] Looking for MinGW Makefiles

[Sisyphus]

Hi,

proj-4.7.0 ships with some makefiles (makefile.vc) that work fine with 
MSVC++.

Does anyone here have any such makefiles that work on Windows with the MinGW 
port of the gcc compiler ?

We can build using MinGW in the msys shell, but msys can be a bit of a 
handful to install (especially the latest version, for which no installer 
exists), and it would be a lot simpler if we can find some makefiles that 
work with MinGW in the cmd.exe shell - written for either mingw32-make or 
dmake.

Cheers,
Rob
