New Revision: 202636
URL: http://svn.freebsd.org/changeset/base/202636

Log:
  Sync unifdefall with upstream. It no longer relies entirely on $PATH
  to find unifdef, in order to support running the test suite before
  installing.

Modified:
  head/usr.bin/unifdef/unifdefall.sh

Modified: head/usr.bin/unifdef/unifdefall.sh
