Yeah, the incompatilibites with msvcr{t,60,70,71,..} is PITA. Also c++
ABI is incompatible.
My solution has been to compile everything using mingw. Most of the
dependencies are (atleast in my case FOSS) stuff, so they are easiest
to compile with gcc anyways.
I'm using cmake with scratchbox to compile software to other
platforms. The windows support of scratchbox is a work in progress but
enough for my use. It uses wine as a cpu-transparency method so
running windows-binaries as native-looking way is possible (try-run
stuff works) eg. I can compile GTK from scratch with it.
The environment is conceptiually similar to cygwin (or closer to
msys), but the platforms are inverted (we are having windows-behaving
environment inside linux box with all native GNU tools) with the
difference is that you can run linux-programs too.

Few months ago I gave few patches to for cmake to get it
creating dlls correctly while being compiled for linux/scratchbox. That has been
enough to have it working, but the concept of using VC with
mingw/msys/cygwin/scratchbox -like system could be an asset for me too.
