I'm not sure this is a bug but it hurts when it bites.

If an enum is seen under extern "C" it gets a different name
for function-parameter encoding than if the same enum is seen
by C++ directly.   

The following session demonstrates.  Note that the linkage name for 
'check' in the nm output at the bottom varies for a.cc and b.cc.
