Hello,

I downloaded djgpp just a few days ago, so am fairly new at it. I have a
bunch of files that I made with Microsoft C++, and when compiled, they
worked fine under that. But when I got them compiled under djgpp and tried
to run it, I got some sort of floating point exception, and signal SIGFPE.
This is the readout I got from symify...

C:\DJGPP\PROJECTS\3D\BOX.EXE BOX.DXF -W

It is a big 3D library, and my guess was that it had something to do with
the floating point calculations ( I think in Panel3D::CalcNormal(), but I
am not sure.) So, if anyone can help me, it would be greatly appreciated.
I'm kinda in the dark here, because I couldn't find a thing in the FAQ.

Also, when I run make, it says something like
(makefile:4) : *** seperator missing

that may not sound weird, but line 4 is:
	cc -c test.exe $(objects)

and if I put a : in, then it only compiles the first .o file in the var
objects. I ended up doing the whole thing, line by line.

Well, if anyone has an answer to either of those questions, it would really
help. 

Thanks in advance,

Luke
