There is yet another way, get the Cygwin binary distribution, which 
contains Win32 versions of stuff we know and love like ln, ls, etc. There 
also is a bash.exe; if you run this stuff under Win95 or WinNT, you can 
have crude symlinks (ln takes care of the .lnk files and crap). With the 
Cygwin binaries (also available, since Cygnus is slow), at

ftp://ftp.admu.edu.ph/pub/gcc_win32

I haven't tried it, mind, but the principle seems sound. You do have to 
get the whole gcc source (2.7.2 is 28Meg untarred!).
