 1.13  16-Jan-2016  christos Add disabled support for saving and restoring the symbol table.
 1.12  20-Mar-2012  matt Use C89 function definitions
 1.11  26-Oct-2009  christos branches: 1.11.6;
resolve conflicts.
 1.10  20-Jun-2004  jmc Completely rework how tools/compat is done. Purge all uses/references to
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')

Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86
NetBSD current (x86 and amd64) and Solaris 9.

 1.9  07-Aug-2003  agc branches: 1.9.2;
Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.
 1.8  31-Jan-2002  tv Protect __RCSID and __COPYRIGHT from being invoked if not defined.
 1.7  14-Nov-2001  tv Pull in various changes from OpenBSD, most from Marc Espie, including:
* Provide some GNUisms as extensions.
* Provide dynamically growable string space.
* Make define(defn(foo)) work correctly for builtins.
(The current version is supposed to be capable of satisfying autoconf.)

All still relevant NetBSD changes have been preserved in this version, and
formatting and style fixes have been applied in various places.

Thanks to Masao Uebayashi <uebayasi@soum.co.jp> for pointing this out.
