New Revision: 219368
URL: http://svn.freebsd.org/changeset/base/219368

Log:
  To be able to use printf extensions we need to turn off gcc format checking.
  Following the convention of NO_WERROR and NO_WCAST_ALIGN add NO_WFORMAT,
  which, when defined in Makefile, turns off compile-time format checking
  (by adding -Wno-format), but still allows to use high WARNS level.
