Makefile.in: define DATADIR, for default owlconf. Makefile.in: provide "all" and "install" rules. configure.in: try also libdes and libkrb4, for people using heimdal configure.in: see if des_ecb_encrypt is already prototyped. configure.in: minor changes to work with new autoconf without needing acconfig.h. configure.in: find the install program. configure.in: test for use_default_colors since some versions of solaris don't have it, so we can at least compile something vaguely working there. keypress.c: ifdefs for keys not defined on at least some solarises. owl.c: don't call use_default_colors if we don't have it readconfig.c: added *commented out* code to try to find a system-default owlconf if the user doesn't have one. Have to ponder if I want this zcrypt.c: don't prototype des_ecb_encrypt if there is a prototype in des.h. zcrypt.c: include owl.h so we get the configure-generated config.h Change to codelist.pl to deal with new code style
