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?
It is not important to me as flags set to BASECFLAGS, CFLAGS, OPT or
EXTRA_CFLAGS will set makefile macros CFLAGS and after distribution
python distutil will use them to build extension modules. So all
variable are equal for builds.
Also after configure without OPT variable set we could check what script
select for build platform and to rerun configure with OPT+own_flags set
on command line (! ;) ) .
