Almost ok.  Please copy the exact text from libgcc2.c for both files  
instead.

Last I checked, it said:

In addition to the permissions in the GNU General Public License, the
Free Software Foundation gives you unlimited permission to link the
compiled version of this file into combinations with other programs,
and to distribute those combinations without any restriction coming
from the use of this file.  (The General Public License restrictions
do apply in other respects; for example, they cover modification of
the file, and distribution when not linked into a combine
executable.)

almost the same, but different.  See http://gcc.gnu.org/ml/gcc/ 
2004-06/msg01828.html for your approval.  :-)
