Use a macro variable PG_PRINTF_ATTRIBUTE for the style used for checking printf type functions.

Browse Source 
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.
