* Did some casts cleaning up to reduce compiler warnings in tif_fax3.c,
from Bruce Carmeron <cameron@petris.com> -- modifications of
changes made by Frank (sun cc still complained on cast).
* Added tiffconf.h to install target per request from Bill
Radcliffe <billr@corbis.com>: "We need a way for ImageMagick to
know features have been compiled into the TIFF library in order to
handle things properly".
