Judging by http://source.winehq.org/git/wine.git/commitdiff/45ead7fe85e7107de91bd79a8ceeb1cb17e4f71d,
Alexandre's preferred idiom is
     static BOOL fixme_once;
     ...
     if(!fixme_once++) FIXME("Report bug to Aunt Tilly\n");

It occurs to me that
#define WINE_ONCE(s) { static int once; if (!once++) s; }
might suffice; you could then write
     WINE_ONCE(FIXME("Report bug to Aunt Tilly\n"));

The previous attempt was more complicated:
