That could very well change. C99 focused on numerical extensions; it is, in
some ways, superior to Fortran 95 for floating-point work. Many C99
extensions are incompatible with C++; see David Tribble's excellent site for
more detail:

I've recently been experimenting with C99 numeric extensions, in conjunction
with OpenMP, using the Intel Linux compiler.

That's what I was trying to convey in my earlier message: The OpenMP syntax
is identical for C and C++. The only differences I found involve additional
requirements in C++ due to the nature of objects (construction, destruction,
etc. for private objects)
