I have several reasons for wanting a free VM. First, I'd like to be
able to test code without compiling under gcj first. I know that gcj +
classpath aren't identical, but that's still better than hoping that
code that runs under Sun's J2SE 142 would work, or even compile. I also
want to make sure that my code (a web server, for one part) is not
somehow linux-only, or specific to a particular VM. Also, while I'm not
sure how big SableVM is, I can't think of a reason that it would be as
big as Sun's JVM. Note: I dual boot Debian Sid and WinXP, where might I
find the ffi files on sid, will I need them if I get checkout from
subversion? Please list exactly what steps you took, and whether you
think they would work on MinGW (more than willing to test them myself).
Of course, MinGW might cause problems (no bash), but --mno-cygwin might
work.

P.S. There's one last reason for a free vm on windows, I use windows
because I'm too lazy to set up a cross-compiler from sid, but I still
prefer free software as a matter of principle, so I never install
anything non-free (other than windows itself, and usually Sun's JVM) on
my system.

Here are my available build-envs:
MinGW w/ gcj + gcj 3.5 and GNU Make (a little difficult to find, but
it's there).
Cygwin w/ gcc + gcj 3.3.
Debian Sid w/ gcc + gcj 3.3 and 3.4.
