   3 # This Makefile fragment is included by package Makefiles and
   4 # buildlink3.mk files for the packages that need a thread-safe
   5 # DNS resolver.
   6 #
   7 # It defines the variables RESOLV_LDFLAGS and RESOLV_LIBS,
   8 # which are also exported into the CONFIGURE_ENV and MAKE_ENV environments.
   9 #
  10 # Package-settable variables:
  11 #
  12 # RESOLV_AUTO_VARS
  13 #       When set to "yes", the necessary flags are added automatically
  14 #       to LDFLAGS and friends.
