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. 19# 20# LICENSE 21# 22# Copyright (c) 2015 Philip Withnall <philip@tecnocode.co.uk> 23# 24# Copying and distribution of this file, with or without modification, are 25# permitted in any medium without royalty provided the copyright notice 26# and this notice are preserved.
