C99 or back to the future

Its almost 10yrs since I had to look at any significant C, and it was pleasant to find that C99 has added:

1. for loop initialisers are supported
2. declarations can be mixed with code
3. there is a bool type
4. the C++ // comment is supported
5. and some weird array and macro stuff (variable length arrays are broken in gcc)

And C style casting was something that I tried very hard to forget.
