There is no C99 syntax mode yet, because the vast majority of C code is C89.

In fact, some folks rely on it not being highlighted, since that will 
fail to compile on many compilers.

We'll need to come up with a new, separate one, because there are a lot 
of other C99ism's than just //.

Fortunately, it's really easy to change this.  Just clone the "cplus 
comment" pattern from C++ mode to C mode.  That will make a faux-C99 mode.
