Perhaps I wasn't that clear in my first mail but the flag '-fsyncc++' is
only there to avoid the duplication of code (I haven't studied the
Objective-C way though). The flag '-fsyncc++' is an internal flag (by
default disabled) which enables the extension. All the modifications for
the sC++ extension is guarded by this flag. There will therefore only be
problems for people who uses the sC++ extension, the C++ language itself
(only the compiler) is not concerned by the change.

Furthermore, the extension is only dependent on the parse.y (and the
lexer files) for generating calls to the kernel. Any other problem
should, I think, be limited to lexical problems such as when a function
changes its name.
