# @BLURB: An eclass to replace some flags in makefiles
# @DESCRIPTION:
#
# @CODE
# To use this eclass, do 2 things:
# 1. append-flags "$MAKEEDIT_FLAGS". If you filter-flags, make sure to do
# the append-flags afterward, otherwise you'll lose them.
# 2. after running configure or econf, call edit_makefiles to remove
# extraneous CFLAGS from your Makefiles.
# @CODE
#
# This combination should reduce the RAM requirements of your build, and maybe
# even speed it up a bit.
MAKEEDIT_FLAGS="-Wno-return-type -w"
# @FUNCTION: edit_makefiles
# @DESCRIPTION:
# Removes some flags in makefiles
edit_makefiles() {
# We already add "-Wno-return-type -w" to compiler flags, so
# no need to replace "-Wall" and "-Wreturn-type" with them.
