Maybe use LIB_PATH or LD_LIBRARY_PATH to find the libraries but the
foo program would need to set the dll path using these environments.
That would only work for dlopen, but not when spawning the process since
that calls CreateProcess, which depends on the Windows DLL load order.
The Windows loader wouldn't even find cygwin1.dll given the above example.
Ugh, winders! How about appending the values of these environments to
PATH prior to CreateProcess and resetting PATH afterward?
