Donn Terry just sent me a note pointing out my incorrect statement. What 
I meant to say was that -fPIC/pic in the usual sense conflicts with the 
MS DLL design, and makes no sense on x86-win32 (except perhaps on Interix).
It involves the issue about static vs dynamic fixup of shared libraries
and so on. Recent GCC versions simply ignore the flag, along with a 
warning, instead of silently creating bad code.

To recap, DO NOT use -fPIC/pic with egcs-1.1 if you don't want bad code.
With egcs-1.1.2 and newer, GCC will ignore this flag, ie, no bad code, 
and tell you that it's being ignored.

Apologies about the confusion.

Regards,
Mumit
