But I were talking about the second one. You should be calling the top-level configure file, yes. However the top-level configure calls gcc/configure (amongst others) and will pass on its command line options, so --enable-languages is a valid switch to use at the top level. See the documentation for a fuller list: http://gcc.gnu.org/install/configure.html Rup.
