How universally is C99 supported?

Question

How universally is the C99 standard supported in today\'s compilers? I understand that not even GCC fully supports it. Is this right?

Which features of C99 are suppo

Answer 1

Look at C99 suport status for GNU for details on which features are supported currently.

Sun Studio is purported to support the entire C99 spec. I have never used them, so I can't confirm.

I don't believe the microsoft compiler supports the C99 spec in its entirety. They are much more focused on C++ at the moment
