GDL license conversion to LGPL

Hi Dave,

In gdl module ( http://svn.gnome.org/svn/gdl/ ), you own the copyright
to following files and have "GPL2 or later" license for them.

gdl/gdl-data-frame.c
gdl/gdl-data-frame.h
gdl/gdl-data-model.c
gdl/gdl-data-model.h
gdl/gdl-data-model-test.c
gdl/gdl-data-model-test.h
gdl/gdl-data-row.c
gdl/gdl-data-row.h
gdl/gdl-data-view.c
gdl/gdl-data-view.h

Would you permit me to change the license to "LGPL2 or later" in
subsequent releases to match with the rest of source files? This would
allow gdl to be released completely as "LGPL2 or later" (currently it is
"GPL2 or later").

Thanks.
