-----------
2009-06-10  Pavel Roskin  <pro...@gnu.org>

        * configure.ac: Remove checks for __bswapsi2 and __bswapdi2,
        they fail without libc headers for the target.
        * include/grub/powerpc/libgcc.h: Use weak attribute for all
        exports.
        * include/grub/sparc64/libgcc.h: Likewise.  Don't use
        preprocessor conditionals.

        build system doesn't need to be aware of the tar.c internals.
