gcc4 allows to check if sentinels are correct (a sentinel is the terminating element in a varargs list). A sentinel needs to be NULL, not 0 - which doesn't make a difference on 32bit but matters on 64bit. Furthermore it can be told that functions have a printf-like format string and argument list so that they can verify that both match. To use these features certain attributes need to be set - which are compiler specific. To do this we define macros which are expanded depending on the compiler version. For now we put those in include/Xfuncproto.h (the XFree86 DDX layer contains a file compiler.h which however is not visible outside the DDX) (Bugzilla #3268).
