The Hurd and gcc 3.4.x part #1

[Alfred M. Szmidt]

The following pops up when compiling the Hurd with gcc 3.4:

../libstore/libstore.so: undefined reference to `__start_store_std_classes'
../libstore/libstore.so: undefined reference to `__stop_store_std_classes'

        * store.h (__start_store_std_classes, __stop_store_std_classes):
        Declared attributes as weak.
        * typed.c (store_find_class): Removed `#pragma weak' for
        `__stop_store_std_classes' and `__start_store_std_classes'.
