If you have a memcpy prototype and -fvisibility-hidden, without any pragmas
around the prototype tweaking the visibility, then this is IMHO a user bug, as
he promises then that memcpy is defined in the current shared library.
To use -fvisibility-hidden with standard headers, one needs to surround them
with pragmas.
