------- Comment #7 from redi at gcc dot gnu dot org 2009-08-28 15:01 ------- it should be --build, not -build
as stated at http://gcc.gnu.org/install/configure.html do NOT build in the source directory, create a new directory to build in and run $SRCDIR/configure instead of ./configure -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41180
