With the enclosed patch, it is possible to build a working emacs under
SunOS 4.1 using malloc.c from the emacs sources.  Just put this line
into config.h:

#define SUNOS_LOCALTIME_BUG

A static function called by tzsetwall clears the byte just past an
eight byte region it mallocs.  Without this patch, that unsociable act
corrupts GNU malloc's memory pool.
