Right now a lot of work is being put into improving g++; I believe that
any code that runs 13 times as fast when compiled with cxx than when
compiled with the current development version of g++ would be of great
interest to the gcc developers. Please consider making your code
available to them; see
http://gcc.gnu.org
for the mailing lists and other information.
