Corinna said, right now I can't have both, so maybe in the future:-). I
think Cygwin can stop handling Win32 paths since we already have
cygpath, so if one want to `rm -rf c:/', one can simply write
rm -rf `cygpath -au c:/`
or simply
rm -rf /cygdrive/c
Sometimes mixing Win32/Posix paths is good, sometimes it's bad. And
things are a bit different now in cygwin-1.7 since chars like
`:' in a filename are allowed.
