------- Comment #2 from kargl at gcc dot gnu dot org 2008-06-20 19:23 ------- Please read the instruction on how to build GCC. Your config.log shows that you are trying to build gcc within its source directory. This is supported.
$ ../configure --prefix=/usr/local --with-mpfr=/usr/local --with-gmp=/usr/local -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36586
