Yeah. In fact, if I adjust most of the format specs to gnu_printf I now 
get exactly five warnings on MinGW64 (down from about 600). All the 64 
bit int format warnings and their cascaded effects dissolve, along with 
the %m warnings.

What I'm thinking of doing is to set up something like:
   #define PG_PRINTF_CHECK __printf__

and on Windows redefine it to __gnu_printf__, and then set all the 
formats to use  PG_PRINTF_CHECK.

Sound OK?
