  Yep.  As far as I know, /bin is superfluous in $PATH and only has to exist
in general in order to support explicit /bin/... shebang paths and the like.
There could be some analogous reason why some apps required it, but I'd not
expect that to arise unless they'd been compiled with $prefix=/, which is of
course wrong for cygwin.
