Some of these files are modified by that script.  If you need to fix a bug in
the code then you should try to get the latest CVS libsigc++ and regenerate
this entire subpackage. If the problem still persists it may be necessary to
modify the generation script.

If an error is found while porting to a new platform read the doc/requirements
