Unfortunately I do not know very much about how GCC defines its target
platform. I stumbled through it once to produce that win32 config file.
One approach is to download the source to GCC 4.2 and try configuring it
under MSys or cross-compiled from a linux machine for the desired target
platform. Then look in the resulting files to see what options it used.
Sorry I cannot be of more help. I'm on another deadline right now.
