Hello,

My program which uses floating-point math fails
in a Win95 DOS Shell when trying to use math
emulation (387=N).  Under a real DOS session,
it runs fine.  I was able to track down the problem,
and apparently any program that uses floating-point
will fail under the above conditions.

A specific example is:

#include <math.h>
int main() {
    float x = floor(-1.5);
    return 0;
}

This has been tested on a Pentium and PPro.
Is this a known problem ?

Thank you for any help.
