Nobody spoke up, so here is the patch that makes zcompile unlink() the
zwc file first and makes it use mode 0444 when creating these files.
Should it use 0400, so that system administrators have to chmod it by
hand?

That hunk in zwcstat() avoids a `unused variable' variable warning if
HAVE_FSTAT is not defined.
