This is nothing to be discussed on avr-libc-dev, as it's simply
a matter of the compiler. So better use avr-gcc-list instead.
However, make sure you're using a recent compiler version! GCC 4.7.2
produces:
$ avr-size foo.elf
text data bss dec hex filename
586 0 0 586 24a foo.elf
vs:
$ avr-size foo.elf
text data bss dec hex filename
368 0 0 368 170 foo.elf
(the latter is the 32-bit version)
