Yes, the hacky patch is fine for you to use, it won't introduce further
problems
(knock on wood! :) ).

Hmmm.  That test is designed to catch local symbols which have already been 
displayed by the normal linker-map-symbol-displaying code.  (eg
__GLOBAL_OFFSET_TABLE__).

Can you give me a specific example of a symbol which is suppressed by this
check, but which should not be ?  (A small test case would be ideal...)
