Hi.
I just bought an old Pentium 90, and it turns out it has the FDIV bug (I
forgot all about that it's been so long).  What is the amount of
compensation for the FDIV bug in NetBSD-1.4.1?  I searched the mailing
lists and found some reference to gcc using a work around, is this still
the case with EGCS (i.e. any code I compile shouldn't be a problem?).  I
assume there is no binary level workaround other than disabling the FPU?

How serious is the bug anyway?  I don't expect to be doing much (if any)
floating point stuff on the machine (it's basically just a NAT box).  Is
it just a few rare circumstanances that result in slightly innacurate
divisions, or is it a good portion of divisions are completely wrong?

Thanks,
	Rick
