I'm not current with snapshots. It's in fact not easy, to keep in touch.
My normal behaviour is, to look into ChangeLog and diff of the snapshot,
to decide, if I need to be current. The decision is simple: If my changes
and the latest snapshot changes are concurrent resp. contrary or overlapping,
I have to check in the snapshots, else not.
Moreover, I'm using CVS, to keep the change history, since I decide, to
download the latest snapshot completely and to check in only _my_ latest
changes into this new snapshot, which I always do under control of CVS.

I have downloaded the development tree of B20.1 in early December, then
I have `./configure' in the tree's root dir. After I have done this once,
I have compiled only, what is interesting to me, especially libio, newlib
etc. Imagine a new winsup: I unpack it into the tree's root dir, cd into it
and call `./configure'. Then I have to open `Makefile' with my editor,
go to the line, which contains

	updir:= $(dir $(srcdir))

which is incorrect because of the local configure call, and change it to

	updir:= ../

I can't remember exactly, because I didn't complain any time, didn't
work instantly but AFAIK, this is one of very few interventions, I had to do.
Maybe, it's my missing insight in the process of automake/autoconf.
But nevertheless, so far, I could compile anything in the development tree.
