I'll do it.  Merging changes requires understanding those changes
and why they were made in the first place, and (except for the
changes to NT_Makefile) since I've done all the merges up to now,
I'm probably best placed for that.

That's correct.

It's important to use the `-I !' option to cvs so that it doesn't
ignore the *.s and *.asm files in the Boehm gc distribution.

You don't need to use the `-m "Log message..."' option
when doing `cvs import'; if you don't specify a log message,
then cvs will start up your editor to let you create one.

Also it's better to do
	
	cvs checkout mercury
	cd mercury/boehm_gc
	cvs update -jgc:yesterday -jgc

(or to just do the two of those three commands in an
already-checked-out workspace) rather than

	cvs checkout -jgc:yesterday -jgc mercury/boehm_gc

since checking out a complete Mercury repository makes it easier to
test your changes.
