Fully agree, although not many compilers are completely C99 conforming. The
more esoteric and generally unsupported features are probably not really
relevant for OpenOCD anyway. Standard library functions and printf
modifiers are not esoteric.

We don't "support" (officially or not) any particular compiler, we adhere
to some (ad hoc) standard, which happens to be a subset of C99 plus some
widely available GCC extensions. Compilers that accept the same language
constructs are more likely to work. All builds are YMMV, IMHO.
"Support" might imply some kind of warranty and OpenOCD does not come with
that. I think the README is already very clear in that MinGW is not
recommended, changing the wording to "support" doesn't add anything.
