# 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.
