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).
