It is not so easy to avoid giving -I/usr/include to gcc.

I am trying to compile gnomemm-1.2.0:

    http://sourceforge.net/project/showfiles.php?group_id=1161

Its configure script tries to compile a gtk-- test program, but
that fails under g++ 3.0.  The -I/usr/include switch comes from
scripts like gtkmm-config or gnome-config, or from the gnome--.m4
Autoconf macro of the gnomemm project.  Actually, those scripts
use an expression like -I$prefix/include, which only becomes a
problem if $prefix is /usr.

I have tried to patch the gnomemm configure script so that it would
take out all occurences of -I/usr/include with a `sed' command,
but I failed and gave up.  It would be much easier if gcc 3.0
behaved correctly, like 2.95.2 did.

Can someone point me to the place in the gcc 3.0 sources where
I could cancel the code that is responsible for this problem?

Thanks.
