	Dumb question:

	Can you post to the mailing list a brief output of your Mingw gcc build using "gcc -v" from the offending Win98 box 
and a Mingw "gcc -v" from the Win2k box?  It may not solve the problem, but at least it will give the members of the list a 
place to start.  I am 90% certain it has nothing to do with your processors.

	Where Mingw is concerned, Win2k is thought of as WinNT.  Win9x platforms handle some things differently and 
do not support certain NT4/Win2k features.
