Hi, http://gcc.gnu.org/gcc-4.0/changes.html mentions that "* The specs file is no longer installed". however, if I locate (modified) specs file at <prefix>/lib/gcc/<triplet>/<version>/specs gcc reads this specs file even without specifying specs= option. Is this behaviour valid, or I should not rely on this behaviour? Thanks in Advance. (Hiroki Kaminaga) t --
