When you use cc in *nix distros is it up to date with the C99 standard?

Depends on what compiler cc actually is.
In Linux, cc is gcc - which has pretty near all of C99's features - I don't really know which parts are missing. I'm sure it's documents on the gcc.org website.

Thanks a lot. Just what I needed.
to compile C99 in gcc, use -std=c99.
But the default is gcc's version of C99 if you don't specify anything, so C99 code will compile OK with that (and then some gcc specific extensions). Of course, if you want to make sure it's C99 compatible, you shold speciy -sdc=c99.Originally Posted by robwhit

gcc's manual says the default it gnu89, not gnu99, and that there are some conflicts between GNU's extensions and the standards. So if you want C99 compatibility fo sho, then use c99, but the default might get you by, like Mats says.
