Changes from release notes:
Version 1.6.3:

  This release corrects some problems in the build process,
  including one that was preventing libtecla from being compiled
  on Mac OS X.

Version 1.6.2:

  This release updates the configuration script to ensure that the
  enhance utility program is compiled correctly on systems that have
  system V psuedo-terminal allocation but not system V streams.

  There are no new features.
