I have just commited a patch which allows using GMP for bignum
computation in 64-bit sbcl on AMD64 (x86_64) processors.
To use it configure using '--with-gmp' option -- you must
have gmp installed (including C header files, that is devel
package), otherwise build will fail.
To get idea of benefits from using gmp, on my machine (2.4 GHz Core 2)
computing 10^6 digits of e takes 15s with sbcl arithmetic, 1.8s when
using gmp 4.2 and 0.6s when using gmp 5.0.
Note: I did all my tests on 64-bit Linux. The code should work on
other 64-bit Unices on x86_64 processors. The code probably will
not work on big-endian machines and certainly would fail in
32-bit mode -- one needs to adapt it to such architectures.
