Yes, libstdc++ support is on the wishlist, even though it's beyond the
scope of the avr-libc project.

Likewise, 64-bit doubles are on the wishlist (as an option to the
current implementation), but again, this is much of a compiler issue
rather than library only.  My preference would be a compiler option
much like we've got -mint8, so perhaps "-mdouble32" which enables the
current behaviour, defaulting to double being 64 bits as this is what
the ISO C standard asks for (well, sort of, but they're asking for
*more* than 32-bit FP for the "double" datatype, and while 48 bits
would satisfy their requirements, it's IMHO not possible to implement
a 48-bit datatype in GCC).

I think the standard feature set of avr-libc is pretty much settled,
and does not call for many more extensions.  (Disclaimer: that's my
very personal opinion.)

Never trust an operating system you don't have sources for. ;-)
