C is a standard language. It has a standard, so all implementers of the compilers must comply with the standard. This standard was called in ages past ANSI C. Today, it is known as ISO C, because it is no longer an American standard, but an international standard.
To be precise, the standard is called ISO C (was called ANSI C) and the language is called C. So in that sense, they are the same.
Is MinGW a good compiler to compile C code? Yes! And don't think any less. It complies with the latest, ISO C99, standard.
