Someone else reported yesterday that a recent version of ld from 
binutils has changed the position of some of the data segments in ELF 
executables, causing problems with unexec. I think it is worth 
investigating if this is really the cause of the gcc 3.3 problems, as it 
could save a lot of debugging.
