[avr-gcc-list] AVR bug fix status


Here is status of the bugs I have looked at.

Bug status needs updating to status in BugzillaFor example, confirm and update known to work/known to fail information.I cannot do this.Some of the bugs are serious and generally I would advise against using4.3 - especially with long operands.Andy
