My Cygwin PATH looks like this:

    PATH=/usr/local/bin:/usr/bin

However I also have an install script that has lines like this:

    ln -s 'c:/program files/gpac/mp4box.exe' /usr/local/bin

This is good because you often *dont* want to be adding these directories to the
PATH. Good example is "C:\Windows\System32". It might have some programs you
want on the PATH (FTP, PING, REG, SETX), but if you add the whole directory you
are going to get collisions (EXPAND, FC, FIND, HELP, RESET, etc)
