Thanks for confirming that this is expected behavior.  I think we should 
clarify this in the GCC documentation (and we have to clean up a few 
bits in the glibc documentation).

Would it be possible to add an ld warning if a hidden reference makes a 
previously public symbol non-exported?

Thanks,
