I successfully just made an uber-installation on Mac OS X including
Mac-Intel 32/64-bit, Linux 32/64-bit, and Windows 32-bit. Applications
made with MAKE_RT there should be able to run on any of those platforms
-- I tested Mac-Intel 64-bit, Linux 32-bit and Windows 32-bit and they
all worked fine. Cool! (Of course the output was 430+ MB.)
