For -# example: -# -# AX_IS_RELEASE([git-directory]) -# AX_COMPILER_FLAGS() -# -# CFLAGS-VARIABLE defaults to WARN_CFLAGS, and LDFLAGS-VARIABLE defaults -# to WARN_LDFLAGS.

EXTRA-*-CFLAGS can -# be used to augment the base and enabled flags. -# -# Warning flags for g-ir-scanner (from GObject Introspection) are -# AC_SUBST-ed as WARN_SCANNERFLAGS. This variable must be manually added -# to the SCANNERFLAGS variable for each GIR target in the code base.
