 Not really, ATTRIBUTE_PRINTF_3 is supposed to be defined as either
gcc-specific __attribute__ expression or nothing at all so unless you
compile with some compiler which pretends to be gcc (i.e. predefines
__GNUC__) but doesn't support __attribute__ I don't know what could it be.
Or maybe it's due to WXDLLIMPEXP_BASE being defined incorrectly but I think
you'd get many other errors in this case.

 Anyhow, as usual, when you get an impossible error like this, chances are
that macros are involved in one way or the other so you should review your
compilation options and maybe examine the preprocessor output.
