And POSIX says "If file contains a <slash> character, the file argument is
used as the pathname for the file. Otherwise, file is used in an
implementation-defined manner to yield a pathname." So I think we are
better off NOT adding an implicit .dll.

My only worry is whether libtool depends on this behavior. But a quick
look at the source code (although not a definitive one) shows that libtool
is already adding a trailing dot on its own, in order to bypass window's
automatic .dll appending. So if anything, I'm guessing that not adding an
implicit suffix is actually what libtool would prefer.
