Try adding the lines:

#include  /* whereever you have main() */
_control87 (PC_53, MCW_PC); /*as the first executed line of main() */

This should force the FPU into IEEE mode which causes 64 bits to be
used (the standard external representation) both internally to the FPU
and externally.  You can get more info on _control87 in
/emx/doc/emxlib.doc.
