Judging by http://source.winehq.org/git/wine.git/commitdiff/45ead7fe85e7107de91bd79a8ce...,
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:

Thanks Dan, I'll try to do something similar.

Thanks for giving a shot too. It's sad that there isn't a macro for
this yet. My FIXMEs are in a loop that might be called thousands of
times (potentially for each vertex in a mesh), so it be could be
extremely noisy.
