With GCC 1.37, 4M was suffient. However, GCC 2.x's memory usage grew with
the version number and 4M is no longer enough. You'll have to add swap
space. Although Linux can swap to a file, swapping to a partition will be
MUCH faster.
To make a file :
dd if=/dev/zero bs=4096 count=<size in k> of=/swap
mkswap /swap <size in k>
To make a partition :
mkswap -c <device> <size in k>
Then do a swapon <device / file> to add it to the system. To have the
swap space added automatically at start up, either add it to /etc/fstab
and put a swapon -a in /etc/rc, or do a swapon <device / file>.

Yes. Note that you should probably use tar instead of cp, since tar
will copy symlinks correctly. You could do something like
mount /dev/sd? /mnt
cd /mnt
(cd /usr; tar cf -) | tar xfp -
Note that this should be done as root.
