Although the cast to void in usage like '(void) printf ("Hello")'
may have been helpful decades ago when Lint Was Your Friend,
nowadays such casts are not helpful. The tz code is currently not
consistent about this: sometimes the casts are present, and
sometimes absent. As they make the code harder to read, let's
remove them.
* asctime.c, date.c, ialloc.c, localtime.c, strftime.c, zdump.c, zic.c:
Don't cast calls to 'void'.
