The #ifdef construct is supported by every C *and* C++ compiler out there.

__cplusplus is defined by *every* standard-compliant C++ compiler out there, 
including Watcom, Microsoft, Borland, Symantec, Sun, and GNU's.

The reason every library does it (including libraries like glib) is because 
it's safe and standard to do so.

For instance, consider the following glib source code (glib/gmacros.h)

/* Guard C code in headers, while including them from C++ */
#ifdef  __cplusplus
# define G_BEGIN_DECLS  extern "C" {
# define G_END_DECLS    }
#else
# define G_BEGIN_DECLS
# define G_END_DECLS
#endif

glib is used on the various UNIX-like platforms, and Windows as well.  Maybe 
even Mac OS X.  And they use the #ifdef __cplusplus guard because it WORKS 
EVERYWHERE, including plain ol' C compilers.

So, thanks for all of your work on the plugin, I'm just trying to put your 
mind as ease about the __cplusplus macro thing, it is not a g++ extension, 
it's standard C++ that will not affect C compilers.
