I'm having trouble building gcc-4_2-branch on Gentoo linux (I can build fine on RedHat and SUSE).
Linux version 2.6.17-gentoo-r8 (root@localhost) (gcc version 4.1.1 (Gentoo 4.1.1)) #1 SMP Fri Nov 3 12:43:16 PST 2006
x86-64 dual opteron box
here is what I use to build:
--prefix=/home/perrin/gcc-4_2-branch/install/$revnum --enable-languages=c,c++,fortran --enable-threads=posix
Here is where the bootstrap fails:
