PatchSet 4613
Date: 2004/04/04 03:03:10
Author: doogie
Branch: HEAD
Tag: (none)
Log:
* scripts/sort-warnings.pl:
* The warnings hash is now a list, so that we can specify the check
order.
* Renamed a bunch of warnings, so they contain the -W parameter
passed to gcc.
* Added several warnings that were being skipped in the log.
* Make a few warnings match multiple lines, to more info is
displayed.
* Fix use of uninitialized value.
