No cross-compilation.

C99 compiler check missing: You can check the compiler support for a
flag with just one line.

pkg-config support broken. My understanding is that it is fixed.

I'm mainly concerned with solving current problems, such as the VC++
build.

I plan to attack MinGW as soon as VC++ is finished. I found the sh/MSYS
problems and think there are workarounds. Anyways, one of the main
reasons for choosing CMake is that reportedly developers listen to their
users and care about fixing bugs.

As already mentioned several times, I don't pretend throwing out the
current build. I want to improve things for VC++ and try to extend this
improvements to the rest of users. You can be assured that your LLVM
build will not fall apart overnight. I don't even have commit rights to
the svn repository.
