happy new year

after way too much time in a port-test-debug cycle
the AT&T Software Technology ast 2012-01-01 beta source release
is ready and has been posted to the download site
        http://www.research.att.com/sw/download/

starting 2012-01-01 we have switched from the opensource Common Public License 
1.0
to the opensource Eclipse Public License 1.0; there is little difference 
between the
two, other than Eclispse seems to be more widely used; this means the license 
acceptance
string has changed (the old one will be accepted for a short period to aid 
transition)
the new string is at the bottom of the license
        http://www.research.att.com/sw/download/licenses/epl-1.0.html

if you dig into the source you'll see a new libast "aso" (atomic scalar 
operations) component
this is the groundwork for migrating libast and the other libraries to 
thread-safety
with this release "cdt" and "vmalloc" are thread-safe; "sfio" is on the TODO 
list

it took us a while to get to this point because we want the same libast binary 
to work
portably, efficiently and correctly for both single and multi threaded processes

we'll wait a week or so for any build problems
and then re-post to the official page
