Hi, Previously, I tryed 2017b like the following.
 make TOPDIR=$HOME/tzdir install
 $HOME/tzdir/etc/zdump -v America/Los_Angeles
It works good .

Now I tryed 2017c as the same way.
 make TOPDIR=$HOME/tzdir install
 $HOME/tzdir/etc/zdump -v America/Los_Angeles
But , zdump outputs  "America/Los_Angeles: No such file or Directory"

Something wrong with me?
