Ok, I've deleted the entire "HKEY_LOCAL_MACHINE\Software\Cygnus Solutions"
registry tree, renamed "c:\cygnus\cygwin-b20\" to
"c:\cygnus-hidethis\cygwin-b20\", and tried to install again.
But, for some reason, it *still* went ahead and created the
directory "c:\cygnus\cygwin-b20\H-i586-cygwin32\bin", stuck
the bin files in there, and pointed the "/usr/bin" registry
key to that.
I manually copied that bin directory to "D:/cygwin/bin" and
changed the registry entry to point to that and now I can
get into Cygwin and a shell.
However, now the problem I have is that when I'm in that shell,
I can't get to /cygdrive/c or /cygdrive/c. An ls on the root
directory reveals "bin cygwin.bat cygwin.ico etc home lib
usr var", but not "cygdrive".
