source: trunk/configure.ac @ 739

Last change on this file since 739 was 739, checked in by Peter Johansson, 13 years ago

fixes #363. Correct AM_CONDITIONAL. Added a warning when configure is run with --enable-debug and help2man is not found. Also added a warning if a bogus man page is created. As before there is a dist-hook preventing that bogus man page is not distributed, however, now the dist-hook is triggered on the AM_CONDITIONAL rather than checking that if the man page is ok. This implies that help2man is required to create a dist also if the man page does exist.
