(GMP_PROG_CC_FIND): Before checking if the compiler knows how to produce 64-bit code, verify that it works at all.

(This code is going to be optimized later.) * New files: gmp.h for GNU specific functions, gmp-common.h for definitions common for mp.h and gmp.h. * Ensure mp.h just defines what BSD mp.h defines. * pow.c: Fix typo for bp allocation. * Rename natural number functions to mpn_*, integer functions to mpz_*. Tue Mar 5 18:47:04 1991 Torbjorn Granlund (tege@musta.nada.kth.se) * mdiv.c (_mp_divide, case 2): Change test for estimate of Q from "n0 >= r" to "n0 > r". * msqrt: Tune the increasing precision scheme, to do fewer steps. Tue Mar 3 18:50:10 1991 Torbjorn Granlund (tege@musta.nada.kth.se) * msqrt: Use the low level routines. Use low precision in the beginning, and increase the precision as the result converges. (This optimization gave a 6-fold speedup.)
