An abbreviation for "those features that aren't in C".

Yeah, that's really unfortunate.  I suppose we'll probably run into it
fairly quickly.

Nevertheless, the restriction to programs that are both legal C89 and
legal C++ of similar vintage has paid off for us, in the sense that we
went from GCC 2.95 to GCC 3.4 without having significant problems
where the compiler suddenly decided our code was unacceptable.
(Similar experience with other vendors' compilers.)  Recently we've
seen a significant rise in warnings that need to be fixed, and
occasional errors, as GCC 4.x has become more common.
