It doesn't work.

It doesn't work either.

Id above. No way.

I've tried even:

%configure CXXFLAGS="-ansi"

and

make CXXFLAGS="-ansi"


It's weird, if I do the same with the tarballs with autotools, always
prevail those flags submitted by the user at configure&&make time.

and the problem stays here: I  mean default flags always go after my
custom ones. Is that deliberately from Fedora packaging system?
