Have you tried running fpc without parameters (to see the complete list)
or looking at our documentation? Anyway, the parameter for link generation
is -Xm.

Interestingly, I just noticed that it doesn't work for OS/2 (it seems that
I've never implemented the required support for that), but there is no
reason why it shouldn't work and I'll fix it.
