# 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.
