This directory includes W. Metzenthen's WMEMU FP emulator.  This
emulator does a much better job in emulating the real FPU than the
stock emu387 emulator supplied with DJGPP.  In particular, trig
functions are more accurate near integral multiples of Pi/4, and the
results for infinite operands match those of a real FPU much closer.

However, unlike emu387, WMEMU is distributed under the GNU GPL
license.  This means that if you distribute your program with WMEMU or
link it against libwmemu.a, your program falls under the GPL, and you
need to make your sources available with the program.

To install the binary distribution, simply unzip the file wmemuNNb.zip
from the root of your DJGPP installation.  To use the emulator, either
link with the -lwmemu switch or set the emu387 environment variable to
point to WMEMU, like this:

	 set emu387=c:/djgpp/bin/wmemu387.dxe

(This assumes that DJGPP is installed in C:\DJGPP on your macgine; if
not, change the above line as appropriate.)  The above line can be
either typed at the command prompt, or you can add it to your
AUTOEXEC.BAT.

To rebuild the library and the emulator, chdir to the directory
linux/drivers/FPU-emu and say "make".  "make install" will then copy
the files into the appropriate directories.
