There seems to be a problem with gcc 4.7.x and ARMv7 platforms. Quite
often
the executable generated won't run with alignment exceptions turned on.
Using '-mno-unaligned-access' to build everything fixes the problem.
It seems there are a few potential problems so it may be
better to stick with GCC 4.1.2 after all.
Is there any compelling reason I should update to GCC 4.7?
If so, is there a way I can set the "-mno-unaligned-access" flag
in the autobuilder so I don't have to change every package?

Alan
