   5 # SYNOPSIS
   6 #
   7 #   AX_COMPILER_FLAGS_GIR([VARIABLE], [IS-RELEASE], [EXTRA-BASE-FLAGS], [EXTRA-YES-FLAGS])
   8 #
   9 # DESCRIPTION
  10 #
  11 #   Add warning flags for the g-ir-scanner (from GObject Introspection) to
  12 #   VARIABLE, which defaults to WARN_SCANNERFLAGS.  VARIABLE is AC_SUBST-ed
  13 #   by this macro, but must be manually added to the SCANNERFLAGS variable
  14 #   for each GIR target in the code base.
  15 #
  16 #   This macro depends on the environment set up by AX_COMPILER_FLAGS.
  17 #   Specifically, it uses the value of $ax_enable_compile_warnings to decide
  18 #   which flags to enable.
