If you have options --with-target-bdw-gc-include= and --with-target-bdw-gc-lib= as well, it overrides the settings done in --with-target-bdw-gc=. This is copied from the setting of the gmp/mpfr options. Any of these options override the automatic discovery using pkg-config. Please suggest a better wording; I thought that was clear enough (and better than the undocumented --enable-libobjc-gc anyway ;) Matthias
