Hi,

Makes sense, for now I am adding this to Pardus Linux gcc 4.2 package to test.

Note that we would need to backport related changes as well (testsuite and libstdc++ fixes). Also while the speedup for the boost MPL testcase is tremendous, "normal" C++ code compile-time and memory-usage is nearly unchanged.

Yep, it only has a big effect on template heavy code. For instance libkdecore changes only from 275MB to 274MB compile memory (-O0 -g).

Ok then not much reason to test it here :). Thank you all for your replies.
