That's surprising given that C++ is more strict in a number of aspects. 
I wouldn't recommend compiling C with a C++ compiler as a general
practice unless the code has been fortified to be C++ type-safe.

__in_bcount_opt is another of those specstrings.h declarators.  If you
look at the top of the file, empty ones are defined for compatibility
for those without specstrings.h, and it looks like somebody just omitted
__in_bcount_opt.  You should be able to just add it.

These all seem to be errors due to trying to compile C with a C++
compiler, since C++ has more strict rules about casting void * and about
const correctness.  Can you please show the output with gcc?
