Looks OK to me.
Just for my peace of mind, can someone assert that -j4 significantly
increases build time even on single-core uniprocessor systems?
Incidentally, why -j4 and not -j2 or -j8?
I've just kicked off this test on my machine (600MHz Celeron, 1GB RAM),
but obviously it won't finish for about an hour:
map time bash -c '{ make maintainer-clean && autoconf && ./configure &&
make 0 darcs ;} &>/dev/null' -- '' -j2 -j4 -j8
