Doubt that's the issue. To summarize, the issues I see are:
* I have an out-of-source build and in-source build. The build system
makes them both conflict and does not do a correct out-of-source build
from then on. I should probably try, let's say a 32-bits in-source
build and a 64-bits out-of-source build and see if conflicts also shows
there too or only when mingw is part of the build.
* mingw creates dependencies that then break the build on Unix (by not
allowing make clean anymore). That Makefile (in or out of source)
cannot be cleaned under a different platform due to path issues. mingw
cross-compiling afaik does not show the path issues. Only a native
windows build does.
* Only real issue with shared libs under mingw is that it creates an
unversioned lib file, which I believe is a build issue (but Mans
disagrees and considers it a "feature" for something that I'm still not
sure what is).
Those three are at least some of the problems I've stumbled so far in
the build system.
