Apologizes, needed to get it out of my chest.

I posted about VC8 back in January 2008:


Taking in consideration was doing what "Average Joe" will do, not
being a VS expert or anything like that.

Wonder how PGO compilation after running the test can improve those values.

Yes, GCC links and target by default to MSVCRT.DLL, which makes
mingw32 binaries compatible with mswin32 ones.

Everything will be great as long both target and use the same CRT.

Now, the issues are Ruby and Ruby code. There are lot of RUBY_PLATFORM
evaluations, so while binaries may be compatible, the Ruby code
perhaps not.

rake-compiler has been created and improved to allow targeting mswin32
and mingw32 platforms, in the aim to maintain backward compatibility
until mingw32 version gets more adopted.
