Use a macro variable PG_PRINTF_ATTRIBUTE for the style used for checking printf type functions.
The style is set to "printf" for backwards compatibility everywhere except on Windows, where it is set to "gnu_printf", which eliminates hundreds of false error messages from modern versions of gcc arising from %m and %ll{d,u} formats.
