ANSI C compliance

Is Visual C++.Net ANSI C compliant?

[Andrew Walker]

The short answer is no, but 7.1 is very close. What they are missing out on is relatively minor at the moment - specifically separate compilation of templates using export. Probably a better question to ask is 'is there another compiler out there better?', and there are some. Intel's compiler is an optimizing compiler, and comeau seems to travel ahead of the pack feature wise. Some of the major compilers are compared in the boost regression tests , although this isn't an entirely fair comparison because of compiler based configuration files and developer mistakes it gives a rough indication of how compilers perform in real world situations.

Yes, but it allows a lot of extensions. Compile with the /TC (Compile as C) and /Za (Disable Language Extensions) options to ensure that you're compiling as C rather than C++, and only using ANSI features. (The other poster is talking about C++ conformance, which is a different thing.)
