svn commit: r273768 - head/usr.sbin/ctld

[Edward Tomasz Napierala]

Author: trasz
Date: Tue Oct 28 10:25:59 2014
New Revision: 273768
URL: https://svnweb.freebsd.org/changeset/base/273768

Log:
  Remove the distinction between strings and numbers from ctld(8) yacc parser.
  This fixes problems with passing strings that look like numbers to clauses
  that expect strings; previously it caused syntax errors and had to be worked
  by user, using quotes.  The workaround introduced in r267833 is no longer
  neccessary.
