I must have missed that discussion (I skip most djgpp messages unless
the subject line indicates something which might interest me).  Since
you seem to be happy with gcc I guess that you are unhappy with the
default action on the detection of an FPU error.  This is probably a
"religious" issue.  I prefer to have the default of having the FPU
cause an interrupt when an error is detected.

netlib is a major source of numeric code.  It is mirrored at a number
of sites.  The main ftp site is (or was) "netlib.att.com", directory
"/netlib".  You should find a pointer there to other, perhaps more
convenient, ftp sites.

Perhaps not, but if the emulator isn't good enough it just compounds
the "problems".
