O.k. I just looked at the grammar and intermixing declarations and
statements became available in C99.  It has been available in C++
for quite a while.

Perhaps...  I'm not really certain I like C99.  I don't have anything
bad to say about it, but with it C is growing and I don't think I
really appreciate that.  

There is actually one good reason to not require gcc 3.x.  gcc 3.x
takes more time to generate larger code.
