This patch is designed to be aplied to Vanilla angband 3.0.1

  It introduces a new compiler flag at config.h : UNIQUE_BLINK
  Defining this flag causes unique monsters to be displayed as a
blinking character.
  Currently this is implemented only for the main-ibm.c platform
and will have no effect when compiling for other systems.
