Minimal change to add a typedef for OS_Status_t, a macro
for constants/literals, and an inline function to convert
to "long" for printing/logging.

Use a separate local variable rather than casting to (void **).

Add feature to generate_stubs.pl input phase to recognize and
skip over `#ifdef __cplusplus` blocks.  This makes it so it
can be used on C headers which are C++-enabled too.
