fix for 1.x MinGW 32/64 build.

Please check commits notes.
I think that the following build instructions should be written on official wiki (http://www.pgrouting.org/docs/howto/build_on_windows.html).

Thanks a lot, Sanak!
Will look at it as soon as possible, but I'm currently at a conference.

Can we then remove this Windows Build manual and replace it with your new one?

The documentation of the pgRoutign website is actually managed on GitHub as well. Here is the source of the Windows Build page: https://github.com/pgRouting/website/blob/master/docs/howto/build_on_windows.rst

Maybe we can find a way to keep the documents (website & BUILD.mingw) synchronized.

Yes, I think replacing to new one is better, because old one use dirty way(direct edit cmake build result .etc).
Should I fork and edit "build_on_windows.rst"?

I think that many other build instructions will be necessary like macports, homebrew, .etc.
So in future, one file may be better like QGIS document(https://github.com/qgis/Quantum-GIS/blob/master/INSTALL).
But now, I think that website(build_on_windows.rst) is enough.
