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