#ifdef HAVE_VARIADIC_MACROS
/*
This is a hack to make it possible to use variadic macros with g++ 3.x even
when using -pedantic[-errors] option: without this, it would complain that
"anonymous variadic macros were introduced in C99"
and the option disabling this warning (-Wno-variadic-macros) is only
available in gcc 4.0 and later, so until then this hack is the only thing we
can do.
