Hi,
I am trying to build GCC 4.9.2 from the SVN sources, but the bootstrap
build always fails with the same error (see below). I configured with
../gcc-4.9.2/configure -v --prefix=/usr/local/gcc-4.9.2 --enable-shared
--disable-multilib --program-suffix=-4.9.2
and I am using GCC 4.8.3 on my system. Any ideas whats wrong here?
