Hmm. Might be a good idea.

I purposely chose the identifier __fuse_t (as an internal identifier)
because I may want to add stuff later. Right now the attribute is "section"
with the named section ".fuse". I'm thinking that it might be a good idea
later on to create an AVR-specific attribute __fusemem__, like we now have
__progmem__, which would put the data in the fuse memory. In doing the new
attribute, then we can create fuse_t as a struct with the new attribute. I
would rather do this kind of change later as it is more intrusive changes to
the AVR port in GCC. With the existing patches, it just changes avr-libc.

So in a sense, having a FUSES macro might be a good way to hide all the
underlying stuff and any changes later on.

Anyone else have thoughts on this?

Thanks for taking a look at this Colin! :-)
