to REL6_4 as well... Use autoconf to determine whether system has POSIX signals, instead of relying on port's os.h to tell us. (Needed for HPUX where system major version is not enough info.) configure unsets USE_TK if X libraries not found. doc/Makefile uses gzcat or zcat as found by autoconf.pull/50/head
