I recently subled upon a problem with GDB. My friend asked me to install DJGPP
on his 386DX40 8MB computer, no FPU. I've written a simple hello proggy to
show him how to debug using GDB. In hello there was a piece of code:

  float  _float1, _float2;

  printf("%f + %f = %f", _float1, _float2, _float1 + _float2);
  test_call();

Now when I set a breakpoint on test_call() and 'run' the program, GDB
signalled that 'Program has exited wit SIGFPE'. I thought I made a mistake
somewhere (?) but the program was working ok from cmdline. Then it ocurred to
me that it might be a problem with the FPU emulation. Is it?
