------- Comment #3 from mmitchel at gcc dot gnu dot org 2005-12-20 16:44 ------- This was discussed after I posted the patch. The GCC format-checking stuff does not know about the Windows extensions. So, on MinGW, you should --disable-werror. This bug should be reclassified as a diagnostic bug; it's a limitation in the format checkers, not a bug in the macros.
