I've been bitten by lack of signature checking in the default extconf.rb
makefile output. Because a function is returning garbage for no apparent
reason it's an extremely difficult bug track down, if you are not aware
that prototype checks are absent.
I've been using $CFLAGS += " -Wall" if CONFIG["CC"] == "gcc".
I would prefer to add -Wstrict-prototypes as well, but this is
incompatible with ruby.h.
Is there portable way for extconf.rb to provide stricter checks, preferably
by default?

using this flag, at least during development.
