I believe we can use something like this to deal with the first problem:

## this sed command emulates the dirname command
dstdir=`echo $dst | sed -e 's,[^/]*$,,;s,/$,,;s,^$,.,'`

The second problem exists in many places in the various configure & install
scripts and probably should be attacked and fixed en-masse.

Michael -- can you verify the sed command I provided above does the right
thing for you?

Also I'd like to have a comment which references dirname (like the one above)
to make these things easier to find (either when updating them to handle
DOS filesystems in the future, or when we need to find a suitable sed command
to emulate dirname elsewhere).

Thanks,
