Hi All,

uname -a
FreeBSD roma.home 7.0-RELEASE FreeBSD 7.0-RELEASE #0: Sun Feb 24
19:59:52 UTC 2008    
[email protected]:/usr/obj/usr/src/sys/GENERIC  i386

I can't compile the subj because I have another "timezone" symbol:
char * timezone(int zone, int dst);

but in widgets/e-timezone-dialog/e-timezone-dialog.c is such code:
#ifndef G_OS_WIN32 /* Declared properly in time.h already */
extern char *tzname[2];
extern long timezone;
extern int daylight;
#endif

I see this is defined correctly on Linux but it is not on FreeBSD.

I've attached my patch.
Though there is probably need something to do with win32, because I
don't know whether there is localtime_r and gmtime_r
