Tested compiler PR patches

[Bryce McKinlay <bryce at albatross dot co dot nz>]

Alex,

I installed your patches for the following PRs into my local tree,
rebuilt libgcj, ran the testsuite, checked that each of the PR test
cases was fixed, and rebuilt my own projects using the patched compiler.
All of these PRs seem to be solved and there were no obvious problems or
regressions caused by the patches. I think they are good to be checked
in, although I might have a closer look at 108 tommorrow...

regards
