Hi Sebastian, Rule #1: do not ./configure in the same directory as the GCC source. Rule #2: do not ../configure from any subdirectory within the GCC source. Rule #3: if Rule #1 or Rule #2 is violated, your source directory is tainted and needs to be deleted and un'tar'd fresh. Make a peer directory to the GCC source. Then ../gcc-source/configure from there. HTH, --Eljay
