_WIN64 is not handled (yet), so we only deal with the "Big 3"
cross-compiler configurations for now, the minimum needed to start
testing on Windows or Linux:
1) x86_64-win32-tcc.exe -> tcc.exe (win32 to Win64/32 only, for now)
2) tcc -m32 -> i386-tcc (Linux64 to Linux64/32).
3) x86_64-win32-tcc -m32 -> i386-win32-tcc (Linux64 to Win64/32).
* I think to get (win64) tcc.exe -> i386-win32-tcc.exe working _WIN64
needs to be defined in the header and elsewhere, about the same way
_WIN32 is. I'll look into that. The i386-win32-tcc is for Linux. ifdef
_WIN32.. else Linux.
I probably should put the "figure out path" part back in using your API
suggestion, thanks. That will make it look much better. I knew there was
something like that. I just couldn't remember the name. I will test all
that for a few days before putting it up. I got another paper to write
now. :(

Yeah, I noticed that, too when I started running tests ;)
