I finally realized why clang has not been silencing its warnings about unused return values: I have -Wno-unused-value set in CFLAGS which comes before OPT (which defines -Wall) as set in PY_CFLAGS in Makefile.pre.in.
I could obviously set OPT in my environment, but that would override the default OPT settings Python uses. I could put it in EXTRA_CFLAGS, but the README says that's for stuff that tweak binary compatibility.
So basically what I am asking is what environment variable should I use? If CFLAGS is correct then does anyone have any issues if I change the order of things for PY_CFLAGS in the Makefile so that CFLAGS comes after OPT?
