Last change on this file since ba0017c was ba0017c, checked in by Daniel Lawson <dlawson@…>, 15 years ago

fixes in configure.in:

  • properly test for zlib
  • use perl -pi -e instead of sed -i
  • improved test for attribute pure, still not quite working - use --without-pure if it fails to test correclty
  • Property mode set to 100644
