Yes, none of that is required any more.  Thanks.

Right - it's a build method that is even less well supported than doing 
an unregisterised bootstrap, because it is rarely needed.  You can 
always do an unregisterised bootstrap first, and use that compiler to 
build a registerised version.  Bootstrapping direct to registerised just 
misses out one stage.

You're in uncharted territory to some extent, because I don't think 
anyone has gone through the bootstrapping process with 6.5 since the 
recent source tree reorganisation.

If you're willing to be a guinnea pig, that's great :-)

I'm guessing the sequence should be something like this:

./configure --enable-hc-boot
$MAKE -C utils/mkdependC boot all
$MAKE -C includes boot all
$MAKE -C rts boot all
$MAKE -C libraries boot all GhcBootLibs=YES
$MAKE -C compat boot all
$MAKE -C utils boot all
$MAKE -C compiler boot all

Try that, and let me know how far you get.
