I was afraid that you may say that.
I am using GrAnd's pre-built Windows environment with gcc 3.4.6 and WinXP Pro.
I do not know anything about Eclipse.
Incidentally, I used the Tools directory from CHDK 1083 because it was already on my system.
Have you tried downloading the source again ?
EDIT
I don't get the rbf or local-time warnings.
local-time may be causing the problem.
EDIT2
Are your and my DISKBOOT.BIN the same size ?
