Ok after searching through FAQs, info files, Dejanews, etc.. I am now
looking for help for this very frustrating problem here. 

I am compiling a program on a 386 (with no FPU) that uses floats.
According to the DJGPP FAQ, I link it with the emulib.a archive to use
emulation. I am also using other archives that I know for a fact were not
compiled with emulib.a but that shouldn't make a difference as far as I
can tell. Now my program doesnt work. I don't want to explain the whole
thing, but basically a function inside one the the other archives (the 
ones that were not compiled with the -lemu option) that uses floats just
crashes inexplicably. Is there something you have to do when creating an
archive from source code to make it use floating point emulation? I don't
understand how emulation can be implemented at link time.

Let me clarify this. First I create an object file:

gcc mylib.c -c -o mylib.o

Where mylib.c uses floats. Then I compile my main source file and link it
with mylib.o and emulib.a:

gcc myprog.c mylib.o -lemu -o myprog.exe

And what I need to know is will the functions originally in mylib.c use
floating point emulation?

Please reply in E-mail to jedediah AT interlog DOT com and thanx.
