Hi again,

how about :

Some {{{make}}} variables are reserved to the user, and the
[http://www.gnu.org/software/libtool/manual/automake/User-Variables.html#User-Variables
Automake manual] and the
[http://www.gnu.org/prep/standards/standards.html#Command-Variables GNU
coding standards] advise to never use them for switches that are
required for proper compilation of the package. When a Debian binary
package is built, environment variables such as {{{CFLAGS}}} and
{{{CXXFLAGS}}} are  set by {{{dpkg-buildpackage}}} and may override the
corresponding variables in the {{{Makefile}}}. We therefore strongly
recommend to follow the above advice.

Have a nice day,
