Proposed changes to localtime.c, zic.c, and Makefile

[Olson, Arthur David (NIH/NCI)]

Here are proposed changes to:

1.	localtime.c, to include "float.h" for the benefit of some gcc
systems (thanks to Bradley White for finding the problem).
2.	zic.c, to complain about links to links if the "-v" flag is used.
3.	Makefile, to ensure that a "make public" is done with the benefit of
gcc diagnostics.
