It turned out some things required for building DLLs were missing from
the configure script and makefiles.  I added them and it seems that it
works now.

If you want to give it a go, get the latest patches from the darcs
repo.  Remember to use libtool 1.5.22 or newer, lest you run to the
--enable-static problem (and possibly others).

This is not entirely correct.  On Windows, two files instead of one
are needed for shared libraries.  One is a dll file (in the bin
directory) and the other is a library file.  

A "make install" on MinGW installs
  bin/libtre-4.dll
  lib/libtre.dll.a

Libtool includes the major version number in the DLL file name, since
Windows does not have real DLL versioning like Unixes typically do.
The .a file is needed to compile applications against the DLL.  At
runtime, only the DLL is needed.
