	* configure.in: Bump version to 0.1.5 for new 64-bit fixes.

	* src/icutil.c (icStipple8Bits): One more fix needed for 64-bit

2003-11-06  Carl Worth  <[e-mail]>

	* configure.in: Bump version to 0.1.4 just to mark removal of the
	version from ic.h, (so not an interesting change and nothing worth
	upgrading to).

	* src/ic.h: Remove IC_MAJOR, IC_MINOR, and IC_REVISION, (which
	were stale anyway so less than useful).

	image->transform.

	"make distcheck"

	type.
