timezonevar in time.h

[Wu Yongwei]

The current /usr/include/time.h requires people to use
"#define timezonevar 1" instead of just "#define timezonevar" before
including <time.h>:

--- time.h.orig	2002-07-06 14:19:00.000000000 +0800
+++ time.h	2002-08-21 21:34:32.000000000 +0800

Change Log:

2002-8-21  Wu Yongwei <adah@netstd.com>

	* time.h (timezonevar): Change "#if" to "#ifdef".


Maybe I still have something wrong here, say, not diffing from the CVS
version (but I really did not find it). I am already struggling to do things
right. :-)
