Several of the conversion routines in cmspcs.c perform explicit comparisons
of double values to 0. Depending on the compiler used and the optimization
parameters, these comparisons can be unreliable. A floating point number may
not be *exactly* 0 - or any other specific number for that matter - although
that was the intent of the program and/or programmer.
