/*
 * FREE GMP - a public domain implementation of a subset of the 
 *           gmp library
 *
 * I hearby place the file in the public domain.
 *
 * Do whatever you want with this code. Change it. Sell it. Claim you
 *  wrote it. 
 * Bugs, complaints, flames, rants: please send email to 
 *    Mark Henderson <markh@wimsey.bc.ca>
 * I'm already aware that fgmp is considerably slower than gmp
 *
 * CREDITS:
 *  Paul Rouse <par@r-cube.demon.co.uk> - generic bug fixes, mpz_sqrt and
 *    mpz_sqrtrem, and modifications to get fgmp to compile on a system 
 *    with int and long of different sizes (specifically MSDOS,286 compiler)
 *  Also see the file "notes" included with the fgmp distribution, for
 *    more credits.
 *
 * VERSION 1.0 - beta 5
