-------------------------------------------------------------------
Looking at this in the larger context, the "|| defined(__cplusplus)"
is useless, as where it is positioned in the file puts it inside of
#ifndef __cplusplus [line 44]
#endif /* !__cplusplus */ [line 66]
The macros are not supposed to be defined for C++, so it ends up
working.  But the extraneous bit should be deleted as it is misleading.
