2005-08-13  Andrew Pinski  <pinskia@physics.uc.edu>

        * Makefile.in (extra_ldflags_libobjc): New.
        (libobjc$(libext).la): Add extra_ldflags_libobjc to the link line.
        (libobjc_gc$(libext).la): Likewise.
        * configure.ac (extra_ldflags_libgfortran): Set for *-darwin* to
        "-Wl,-single_module".
        * configure: Regenerate.
        * linking.m (_objcInit): Remove.
