I don't think there is risk of regressions, but I'm not very familiar with where PCH is used. However, I'm told it is not very much used. Alternatively we could time how much time the stdc++ PCH actually saves (if anything?) during make check, and kill it altogether for 4.6. Paolo -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40974
