I don't think so. There's many other compilers out there that doesn't support C99 features, and most of the git source code does not depend on them. IMO, it is better to fix these issues for all those compilers once and for all, instead of having to find ways of working around them whenever someone changes compiler.

Besides, C++ isn't a strict superset of C. There might be warnings or errors introduced by compiling the code as C++. Implicit conversions from void* springs to mind. Quick tests reveals that MSVC doesn't seem to warn or error about them, but there might be some other differences where we do get into issues.
