To answer the question in the subject: no, /lib isn't needed in $PATH.

For precisely this reason, Cygwin's DLLs that are loaded via the Windows
dynamic loading mechanisms are in /bin.  There shouldn't be any "linked"
DLLs in /lib.

If a program places its DLL under /lib, it should modify the environment
appropriately so that the Windows loader finds it, or use the Cygwin
loading mechanisms (i.e., dlopen()).

Which DLLs in /lib cause problems for you if /lib isn't in the $PATH?
