From: "Markus F.X.J. Oberhumer"
Subject: [SDL-CVS][patch] add missing SDLCALL to headers
the small patch attached below (against current CVS) adds some missing SDLCALL
decorations to callback types and arguments.
Unfortunately one of these changes breaks your gen{def,exp}.pl scripts which
should be changed to use non-greedy regular expression matching...
