Use configure with --enable-languages=c This means only the C compiler is built. No C++, no Fortran, Objective C, etc... Of course you need a working C compiler to compile GCC. I don't know what system you're working on, but later versions of Linux distributions should have a new enough GCC to compile GCC from source. Also of note, the way GCC is currently built is such that the installation is relocatable. Say you install it into /usr/local/gcc. Then you can take the entire contents of /usr/local/gcc and move them to /opt/gcc and what is in the new location will Just Work (TM). Tom
