Dean Camera wrote in Comment #3, bug #37104 (project avr-libc):

can upstream GCC not use the patches Atmel provides in their toolchain

The patches must be used atop whatever version Atmel used to build their
release, presumably something like gcc_4_6_2_release in


The farther away to the original version the actual GCC version is,
the likelier you will get merge conflicts, you might unintentionally
break the compiler, or the patch is so completely outdated that you
have to rewrite the feature from scratch.

For example, if you try to apply the patches from your tool chain
against 4.7 or trunk, you won't have fun...
