* Implement automatic detection of gcc version 3 and apply the gcc3
  patch in configure.
* Apply a patch for compilation on Apple/Darwin (without gcc3).

Changes since version 1.3.0
* Fix the following bug: a repository inconsistency could arise when
  a checkin operation is aborted after the project's RCS version file
  has been updated but before the PRCS repository data file is updated.
* Fix a partial-checkin bug.
* Fix bugs related to deleted project versions.
* 'prcs info' now now prints summary information for deleted project
  versions.
* Patches have been included for compilation with GCC 3.0.x.
* Debian packaging.
* prcs.el improvements.
* prcs usage() reports to stdout instead of stderr.
* prcs.texi bug in 'prcs execute' example.
* contrib/prcs-clean improvements.

Changes since version 1.2.16
* Add new command 'prcs changes' command.
* Support for the new 'changes' command.
* Add new --version-log= option to 'prcs checkin'.
* Add new contrib package 'pck'.
* Add a new --no-keywords option to 'prcs populate'.
* Updated 'prcsutils' contrib package.
* Updated 'visualtree' contrib package.
* Fix a keyword-substitution bug.
* Upgrade to regex sources from glibc-2.2.4 for 64-bit support.
* Remove a declaration of abort() that was conflicting with the
  headers in RedHat 7.x and causing compilation problems.
* Fix for non-existant user/group handling in 'prcs admin access'
* Fix for checkin and merge commands to preserve the project file
  mode.
* Fix prcs.el to support Emacs 21.
* PRCS checks for proper versions of RCS and GNU diffutils before
  running--these checks were broken by GNU diffutils 2.7.2 and are now
  fixed.

Changes since version 1.2.15
* Incorporate new contrib submissions (rprcs, prcs-synch, visualtree,
  pfe and prcsutils).
* Previously, 'prcs config' would perform a sanity check on the
  configured RCS and diff commands to see that are indeed the GNU
  versions of those commands.
* After a successful merge, list all files which have merge conflicts.
  Merge "No Prompt" actions are now silent unless -L is specified, and
  "Do Nothing" actions are silent when -f is specified and unless -L
  is specified.
* Improve error reporting.
* The documentation stated that `:' was a valid character for major
  version names, although the program has never accepted this character.
