Sure, considering that following is way better:
# These files are to have specific diagnostics suppressed, or are not to
# be subject to -Werror:
# flex output may yield harmless "no previous prototype" warnings
build/gengtype-lex.o-warn = -Wno-error
gengtype-lex.o-warn = -Wno-error
expmed.o-warn = -Wno-error
