I finally got a response on *why* the distdir was chmod'ed '-R a-w' 
It's because the test is to see if a distribution (of the package you're 
automaking) will operate correctly if the sources are on a read-only 
medium.  Thus, preserve time stamps, but make sure EVERYTHING is read-only.

I'm not sure how this would interact on FAT drivers, or NTFS/nontsec. 
Its probable that 'cp -p' would just do its job and return without 
error, and automake would be none the wiser.  Maybe that's what cp -p 
should do -- just ignore the ENOACCESS that the SetFileTime() function 
returns?

One person on the automake list suggested:

BTW, with NTFS/ntsec (Aug 11 snapshot), I can

mv foo bar

successfully, even if foo is -r--r--r-- (I own foo).
