I have uploaded my improved '387 emulator to simtel. It should
appear as:
            msdos/djgpp/wmemu111.zip

Here is the description which I sent with the upload:

wmemu111.zip contains a replacement emu387 for djgpp version 1.11.
It is based upon wm-FPU-emu (the FPU emulator of the Linux operating
system) and inherits most of the features of that emulator:
 (1) implements essentially all of the functionality of an 80486 FPU,
including un-documented op-codes,
 (2) produces exact (i.e. max error of 0.5 ulp) results for all of the
basic arithmetic functions (+,-,/,*,sqrt),
 (3) produces exact results for the remainder instructions (fprem,
fprem1),
 (4) obeys all of the applicable control word bits,
 (5) sets all applicable status word bits, and
 (6) provides superior argument reduction for the trig instructions;
pi is approximated to approx 128 bit precision versus approx 66 bits
of an 80486 FPU.
The source code for the emulator is included.

Special requirements: 80386 or higher cpu, software driver such as
go32 from djgpp 1.11.
