Definitions for GNU multiple precision functions: arithmetic with
integer, rational and real numbers of arbitrary size and precision.

Translation of the C header (gmp.h) of the GMP library. Tested with
GMP 2.0.2 and 3.0.1.

To use the GMP unit, you will need the GMP library which can be
found in ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/libs/ .

@{ If this define is set, routines new in GMP 3.x will be made
  available. The define will have no effect on the other interface
  changes between GMP 2.x and 3.x, i.e. the other routines will work
  correctly even if this define is set incorrectly, except on 64 bit
  machines, Crays and other systems where the types are different
  between the GMP versions. Otherwise, the only possible problem if
  setting the define while using GMP 2.x are linking errors if you
  actually use any of the new routines. @}
