Hi!
Thanks for catching this. I've pushed a bit different patch that fixes
also the -w option.

Hm, passing CFLAGS to configure should work as:

CFLAGS="-W -Wextra -O0 -ggdb" ./configure

But looking at what we have in LTP there are OPT_CFLAGS and WCFLAGS
which adds the -O2 and more. So at the moment you have to modify CFLAGS
manually in the include/mk/config.mk.

Does anybody have an idea why the CFLAGS are split among three variables
to optimizations and warnings? It does no make much sense to me. There
is only one place in the source tree where these are redefined, I will
check if that is really needed and possibly get rid of this mess. Is
anybody opposed?
