Log Message:
Update to GNU MP 4.2.1

Changes between GMP version 4.2 and 4.2.1

  Bugs:
  * Shared library numbers corrected.
  * Broken support for 32-bit AIX fixed.
  * Misc minor fixes.

  Speedups:
  * Exact division (mpz_divexact) now falls back to plain division for large
    operands.

  Features:
  * Support for some new systems.

Changes between GMP version 4.1.4 and 4.2

  Bugs:
  * Minor bug fixes and code generalizations.
  * Expanded and improved test suite.

  Speedups:
  * Many minor optimizations, too many to mention here.
  * Division now always subquadratic.
  * Computation of n-factorial much faster.
  * Added basic x86-64 assembly code.
  * Floating-point output is now subquadratic for all bases.
  * FFT multiply code now about 25% faster.
  * Toom3 multiply code faster.

  Features:
  * Much improved configure.
  * Workarounds for many more compiler bugs.
  * Temporary allocations are now made on the stack only if small.
  * New systems supported: HPPA-2.0 gcc, IA-64 HP-UX, PowerPC-64 Darwin,
    Sparc64 GNU/Linux.
  * New i386 fat binaries, selecting optimised code at runtime (--enable-fat).
  * New build option: --enable-profiling=instrument.
  * New memory function: mp_get_memory_functions.
  * New Mersenne Twister random numbers: gmp_randinit_mt, also now used for
    gmp_randinit_default.
  * New random functions: gmp_randinit_set, gmp_urandomb_ui, gmp_urandomm_ui.
  * New integer functions: mpz_combit, mpz_rootrem.
  * gmp_printf etc new type "M" for mp_limb_t.
  * gmp_scanf and friends now accept C99 hex floats.
  * Numeric input and output can now be in bases up to 62.
  * Comparisons mpz_cmp_d, mpz_cmpabs_d, mpf_cmp_d recognise infinities.
  * Conversions mpz_get_d, mpq_get_d, mpf_get_d truncate towards zero,
    previously their behaviour was unspecified.
  * Fixes for overflow issues with operands >= 2^31 bits.

  Caveats:
  * mpfr is gone, and will from now on be released only separately.  Please see
    www.mpfr.org.
