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