GCC / CLang offer checking for consistency between format strings and the variable argument parameters that
are passed to printf-like functions. For these compilers, we add the necessary function attribute (use with -Wformat).
For MinGW, we have to be a bit more specific, as both a STDIO implementation by Microsoft as well
as a POSIX compatible implementation are supported. Generally, for C++, the POSIX library is used. We check the
MinGW compiler definition that selects the STDIO implementation and use the corresponding format specification
(gnu_printf vs ms_printf).
