the old code updates things based on the info in VERSION. I've
kept this, but added a second token in VERSION, "beta". configure
will now parse VERSION into $VERSION and $RELEASE. Whatever the
second token is will be appened to the "release" target tar and
zip afiles, and will be used by dist/newversion to
create dist/tiff.version.
* 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".
