I haven't used Moshier's long double routines, but I have been favorably
impressed with others of his, and on that general basis, I would expect the
long double routines to work well, too.

One other poster asked whether Borland C++ long doubles are more precise
than DJGPP doubles.  On BC++, as on DJGPP, long doubles are 10-byte
variables with a 64-bit mantissa.  This matches the internal format of the
coprocessor.
