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

Microsoft appear to be tracking C++ standards, but have no support for C99. (They may cherry-pick some features, but could be said to be cherry-picking C++0x where there's an overlap.)

As of Visual Studio .NET 2003, new projects have the 'Compile C code as C++ (/TP)' option enabled by default.
