I'll go out on a limb and say that all UNIX/POSIX platforms expect /bin
and/or /usr/bin to be in your path if you're not specifying an absolute
path when invoking your binaries.  This is not an unusual expectation
and isn't confined to the UNIX/POSIX world.  There isn't any "fix" that
will be forthcoming in the Cygwin DLL that will change this expectation,
though there may be others on this list that have some clever workarounds
that you could try.
