I'm having problems with visibility attributes and ld scripts. For instance, 
the following program (test.c):

extern __attribute__((visibility("internal"))) void *__foo;
void* f(void) {
        return __foo;

compiled with the following script (test.lds):
        .data: {
                __foo = .;

compiled with

gcc-4.0 test.c test.lds -o libtest.so -shared -fPIC

produces the following error:
/usr/bin/ld: /tmp/ccUpkjLi.o: relocation R_X86_64_PC32 against `__foo' can not 
be used when making a shared object; recompile with -fPIC

This happens because __foo isn't defined as being internal in the linker 
script. Is there a way to do this? (I couldn't find in the info pages).
