--- Comment #1 from Jack Howarth <howarth at nitro dot med.uc.edu> 2010-12-09 18:12:48 UTC --- This problem no longer exists on x86_64 Fedora10 with gcc trunk at r167647, however building with... ../gcc/configure --with-gmp=/usr --with-mpfr=/usr --with-mpc=/usr --prefix=/home/howarth/dist --enable-languages=c,c++ --enable-build-with-cxx also no longer results in cc1-dummy being built (whose linkage caused the previous bootstrap failure).
