I would think this is more likely a fault in the headers / declarations - i.e. 
there is some ambiguity in there. GCC tends to be more tolerant of these things 
than most other compilers - which is good in some cases, but bad if you're 
trying to compile the same code using a compiler that's more "by the book".

True, but you shouldn't have to do this if LD defined to be CC rather than 
/usr/bin/ld since CC does this automatically.

Yep, but it's this weirdness that makes people prefer not to use C++ - not to 
mention the name-mangling that goes on in the libraries which tend to be 
incompatible between compilers :(
