The only place where this is strictly needed is in log.cpp where one
needs to handle a variable number of arguments.

There are a few possible solutions:

1. Does changing the include from <stdarg.h> to <stdarg> help?
stdarg.h is deprecated for C++ so this should be done anyway.

2. Does vsprintf() work as an alternative to vsnprintf()? The
difference is that for vsnprintf() one can set a limit for the size of
the buffer used (but we can get around this by manually checking the
string length).
