Currently, on the various windows platforms, shlibpath_var is set to PATH,
so setting shlibpath_var does indeed override the runpath (in a manner of
speaking).
There are two ways to fix this:
i) deem that $PATH is _not_ the shlibpath_var and leave it unset.
ii) set shlibpath_overrides_runpath=yes to indicate that this works:
$ PATH=/where/all/my/dlls/live:$PATH foo.exe
The second looks correct to me... and libtool seems to agree with me ;-b
Cheers,
Gary.
