I did a full compile of 2.4.8-pre3 for i386, after suppressing 117
config entries that generated error messages.  Another mail will
contain the error information.

Even after removing all the code that will not compile at all, there
are still a lot of warning messages in 2.5.8-pre3.  I offer this list
in the hope that the maintainers will fix the code (I can dream, can't
I?).  No need to copy me on replies, just fix the code.
