GMP 4.1

Version 4.1 of the GNU Multiple Precision Arithmetic Library (GMP) has
been released.  The source code is available from

        ftp://ftp.gnu.org/gnu/gmp/gmp-4.1.tar.gz

Many sites around the world mirror ftp ftp.gnu.org, please use one near
you.  See http://www.gnu.org/order/ftp.html for a full list.

GMP 4.1 was finished and released by Torbjörn Granlund and Kevin Ryde.
See the GMP manual included in the sources for a complete list of

Changes between MP version 4.0.1 and 4.1

* Bug fixes.
* Speed improvements.
* Upwardly binary compatible with 4.0, 4.0.1, and 3.x versions.
* Asymptotically fast conversion to/from strings (mpz, mpq, mpn levels), but
  also major speed improvements for tiny operands.
* mpn_get_str parameter restrictions relaxed.
* Major speed improvments for HPPA 2.0 systems.
* Major speed improvments for UltraSPARC systems.
* Major speed improvments for IA-64 systems (but still sub-optimal code).
* Extended test suite.
* mpfr is back, with many bug fixes and portability improvements.
* New function: mpz_ui_sub.
* New functions: mpz_export, mpz_import.
* Optimization for nth root functions (mpz_root, mpzperfectpower_p).
* Optimization for extended gcd (mpz_gcdext, mpz_invert, mpn_gcdext).
* Generalized low-level number format, reserving a `nails' part of each
  limb.  (Please note that this is really experimental; some functions
  are likely to compute garbage when nails are enabled.)
* Nails-enabled Alpha 21264 assembly code, allowing up to 75% better
  performance.  (Use --enable-nails=4 to enable it.)
