building snapshots.... noob enquirey

Hi All

Having successfully build the recent 4.6.2 release of g++ I thought
I'd try for a 4.7 snapshot, as
I'd like to try out some of the new C++ features.

Am I correct in believing that snapshots include everything for all
supported languages, rather than
the just the core & g++ bits I've built before? And consequently
building snapshots takes a while?
Is there anyway to download and build just those bits I'm interested
in, as I would for a release?

My build eventually failed with this....

rm -rf asm classes classes.lst asm.lst

make: *** [all] Error 2

which I think is from building something I'm not really interested in.
Can I get past this failure?

I'm building on Fedora 13, 64bit.

Thx,

- Rob.
