ATmega16U2 is supported by avr-libc, provided your compiler has been
patched to support it.  Presence of respective compiler support is
autodetected when running avr-libc's configure script, and the
respective pieces are omitted if the compiler support is missing.

I don't have an idea whether the AT90USB162 and the ATmega16U2 are
binary (probably upwards) compatible; however, usually there are
application notes available describing that kind of migration process.
Please see whethere there's one around for this transition, and what
it has to tell about binary compatibilty.  Of course, if they are
binary compatible, you could just compile the code for an AT90USB162
(which is likely to have better support even in somewhat older
toolchain versions).
