Our internal SQL-based bug database lets you do it, indirectly.  The
bug state can only be OPENED, ASSIGNED, FIXED etc like GNATS, but there's
also a field for the release containing the fix.  Given something like
this, it's not difficult to write an SQL query that shows all outstanding
bugs on the 3.0 branch, as you would also include bugs marked FIXED
if the fix release were set to 3.1.  This would require, though, that
the bug database be updated when a fix is back-ported.
