I am trying to run a C program compiled with the
DOS djgpp compiler gcc-2.2.2.

Whenever I call any of the functions in math.h (log(), sqrt()...),
I get the error:

   Segmentation violation in pointer 0x00000004 at 40:b0003264
   Exception 14 at eip=b0003264

My computer does not have a 387 coprocessor; instead, I am using
the 387 emulator emu387.  A line from my autoexec file is

set GO32=emu c:/djgpp/emu387/emu387

I always #include <math.h> when trying to call the math functions,
and always use the -lm compiler switch.
Are there any other clues I need to use functions from libm.a with
the EMU387?

I greatly appreciate people's help.
