I do agree it's much polite and cross platform, but doesn't seem to work in Windows XP Pro (only tested in WinXP Pro SP2) with GL 3.2 and FPC 2.0.2 (I've looked everywhere down my PC for a version number, but not found :-), I guess it oughtta be 4.1 but I can't stand for it). Anyway using Set8087CW (which is indeed CPU dependant) does work under my equipment, SetExceptionMask doesn't.

Just to make it know (as a primarily Win NT user). I really don't know whether it is as it should be or it should be fixed :-?. A plain Win user as me normally use syscalls to the API, but I'm afraid it's comprimising compatability issues. Masters will tell, I hope :-)
