You could also use MinGW shell coupled with Eclipse for C/C++.
Builds can be reduced to a few button clicks.

This way, if you need to use different #defines and versions you can have separate projects with linked source folders.

I am happy to help you achieve this, and I can send you docs - you might discover a few tricks that elude me.

Enclosed is a screen shot revealing what can be achieved.

Hope it helps.

But hey, it's free software. If you wanted to write and maintain an
alternative set of build scripts to work with different versions of
mingw, that would be great.

I'm using the top of the line version of MingW (v3.18). I don't think
MingW has changed too much the last 5 years that it would matter for Tor. Except for the added gettimeofday() (in MingW v.316 I believe), an
orconfig.h should be unaware of any MingW version.

I'd greatly
prefer a separate orconfig.h if you take this route: sharing the same
one between msvc and mingw seems like it's asking for trouble.

Okay, but I'm now building Tor with the attached orconfig.h. This has
"only" 5 tests for __MINGW32__. I don't think that is asking for trouble.
