The usr/bin or usr\bin folder is normally created when you first install
(via setup) and is a cross-mount to /bin in cygwin as is /lib and /usr/lib .

Now the fact that you don't have a lib dir too is puzzling :/ It's not
really a problem as such all you need to do is create a bin and lib dir in
/usr (c:\cygwin\usr).

What there is, is two physical dirs c:\cygwin\bin and c:\cygwin\usr\bin .
One of these (c:\cygwin\bin) contains all of your programs, dlls and such
with the other (c:\cygwin\usr\bin) being empty. This is because /usr/bin
(c:\cygwin\usr\bin) is mounted as c:\cygwin\bin (/bin). I've been all round
the house's with this so hope I haven't made you loose the plot with this
one ;-)

An even quicker and dirtier trick would be to edit your /etc/profile to
exclusively set up the HOME environment variable. That way it's going to be
set and you'll find yourself in your home directory when you start bash.

It does for some :-)
