[Gcl-devel] GCL 2.6.10 has been released

[Camm Maguire]

Greetings!  The GCL team is happy to announce the release of version
2.6.10, the latest achievement in the 'stable' (as opposed to
'development') series.  Please see http://www.gnu.org/software/gcl for
downloading information.

This release addresses many of the issues introduced by the 2.6.9
developments, in addition to using gmp for random number generation,
adding fast immediate fixnum operations for most functions, and
accelerating garbage collection and hash table lookups.  From the git
