See <http://gcc.gnu.org/bugs.html> for instructions. make[3]: *** [build/gengtype-lex.o] Error 1 This might be identical to PR rtl-optimization/37333. I'm currently running a mainline bootstrap as of 20080908 to check.
Subject: Re: [4.4 regression] IRA merge breaks Tru64 UNIX bootstrap After applying the patch for PR rtl-optimization/37333 from http://gcc.gnu.org/ml/gcc-patches/2008-09/msg00514.html and applying http://gcc.gnu.org/ml/gcc-patches/2008-09/msg00705.html I'm now past stage3 and into building the target libs. So it seems that this PR can be closed once the patch is checked in. Rainer
Both patches have been checked in, so closing as fixed. (We're back at PR bootstrap/36851 now, though.)
