  Modified files:
    usr.bin/make         var.c 
  Log:
  Prevent infinite substitution of the empty string by forcing non-
  global substitution. In general it's a makefile bug to globally
  substitute the empty string, but it's a bug in make(1) if a bug
  in the makefile yields an infinite running time of make(1).
