I don't have Visual Studio 6.0, so I can't build it with msvc the 
official way. And in my experience (well, with 1.8.7) ruby compiled with 
vs2008 express was too unstable, so not even worth a try.

Mingw compiled 1.8.6 has some strangeness in that make test-all has 
tests that sometimes complete normally, and sometimes show up as E or F. 
But I never could complete it to the end, because it always hangs up in 
rb_w32_select, in one test or the other.

Yeah, I experienced some problems with gcc 4.3 several months ago (not 
ruby related though, I wasn't even into ruby at that time), so I fell 
back to gcc 3.4.5 (latest mingw that is not 4.3) ever since. But I tried 
compiling ruby 1.9.1 with gcc 4.3 once, and it had compilation error in 
one of extensions. I was too lazy to investigate, so reverted back to 
3.4.5 without even trying to come up with any fix.

Wow, thanks for the link, I'll be sure to try if it would allow me to 
complete ruby 1.8.6 tests...
