The 387 emulation library seems to have a problem.  I compiled the
little program below with gcc2.95 and DJGPP, using the following
command lines in an MSDOS 6.22 OS on a 486SX25:

gcc -s -O2 -Wall -c sqrt.c
gcc -s -O2 -Wall -o sqrt.exe sqrt.o -lemu

No errors or warnings appear during compilation or linking.  Running
the resulting program (SQRT.EXE) produces no output at all, and I was
able to terminate the program with CTRL-C.  Here is the program
source:

==============================cut here==============================

/*Demonstrate the EMU387 error.*/

#include <math.h>
#include <stdio.h>

int main (void) {
  printf ("%g\n", sqrt (2.0));
  return (0);
}     /*main*/
