 * $Log: configparse.c,v $
 * Revision 1.10  2003/03/01 06:55:39  npetroni
 * modified config parse to use lex and yacc for parsing. this may break stuff temporarily, but is good in the long run
 *
 * Revision 1.9  2003/02/11 00:25:21  galimorerpg
 * GCC 2.95.3 Fixes.
 *
 * Revision 1.8  2003/02/10 00:16:51  galimorerpg
 * Configuration parsing checks.  We now recover from some potential segfaults.
 *
 * Revision 1.7  2003/02/03 18:03:33  galimorerpg
 * ChangeLog updates.
 * Better errorchecking in configparse.c
 *
 * Revision 1.6  2003/01/14 23:52:07  chessing
 * More work on the TLS code.  It should be mostly stable now.  There is a problem if get_pass("") in eaptls_auth_challenge is called twice.
 *
 * Revision 1.5  2003/01/09 20:50:15  chessing
 * Code cleanups.
 *
 * Revision 1.4  2003/01/09 20:17:25  galimorerpg
 * Logging Updates
 *
 * Revision 1.3  2003/01/03 22:25:35  chessing
 * Turned off debugging code, (use the configure options to turn on the debugging) and added -w option to get around some problems with the Intel iANS drivers, and some wired/wireless issues with the MacOS-X wireless code.
 *
 * Revision 1.2  2003/01/02 19:29:37  chessing
 * Update to bring the xsupplicant code current with the development work.
