To clarify: I used my android branch and compiled linux 32/64-bit and
windows libraries using it to get a multi-target FB installation.

Also, I forgot to mention that recently when I tried to compile
ohrrpgce-game for Android I found it would crash when entering BROWSE(). I
didn't figure out why yet. I wonder whether it's due to something that went
wrong when I last merged upstream master into the android branch, back in
June. I think I must have successfully compiled for Android more recently
than that though. Would like to hear whether it works for you. I haven't
tried again since doing the latest merge.
