[Gcl-devel] Re: [Maxima] Requesting input on some possible low-level changes

[Camm Maguire]

Greetings, and thanks as always for your feedback.  I cannot reproduce
this with the current 2.6.1 cvs build, recently released as a Debian
package.  (ftp.gnu.org is *still* down, so in the interim, we will be
using cvs and the Debian pool as our means of distribution.  We have
also moved to a linux kernel style release naming convention.  x.y.z,
with y *even* is stable, y odd unstable/development.  So basically
we've renamed the pending 2.5.4, never released, to 2.6.1.)
