7# makeedit eclass, will remove -Wreturn-type and -Wall from compiling, 7# To use this eclass, do 2 things:
8# this will reduce the RAM requirements. 8# 1. append-flags "$MAKEEDIT_FLAGS". If you filter-flags, make sure to do
9# the append-flags afterward, otherwise you'll lose them.
10# 2. after running configure or econf, call edit_makefiles to remove
11# extraneous CFLAGS from your Makefiles.
12#
13# This combination should reduce the RAM requirements of your build, and maybe
14# even speed it up a bit.
