- be defined when we're using X11R5, since X11R5 has the features of
- X11R4. If, in the future, we find we need more of these flags
- (HAVE_X11R5, for example), code should always be written to test
- the most recent flag first:
-
- #ifdef HAVE_X11R5
- ...
- #elif HAVE_X11R4
- ...
- #elif HAVE_X11

-
- If you ever find yourself writing a "#ifdef HAVE_FOO" clause that
- looks a lot like another one, consider moving the text into a macro
- whose definition is configuration-dependent, but whose usage is
- universal - like the stuff in systime.h.
-
- It turns out that we can auto-detect whether we're being compiled
- with X11R3 or X11R4 by looking for the flag macros for R4 structure
