New in 1.3: 1999-04-??; CVS version 1.2g, Libtool team:
* AM_PROG_LIBTOOL is smaller and faster
* AC_LIBTOOL_WIN32_DLL is required in configure.in for libtool to
attempt to build dlls on win32 hosts
* Shared libraries on AmigaOS up to version 4 are now disabled
since they don't meet libtool's requirements for shared libraries
* -L supports now relative directories

Enable checking for dlopen support. This macro should be used if
the package makes use of the @samp{-dlopen} and @samp{-dlpreopen} flags,
otherwise libtool will assume that the system does not support dlopening.
The macro must be called *before* @code{AM_PROG_LIBTOOL}.
The macro must be called @strong{before} @code{AM_PROG_LIBTOOL}.

@defmac AC_LIBTOOL_WIN32_DLL
This macro should be used if the package has been ported to build clean
dlls on win32 platforms. Usually this means that any library data items
are exported with @code{__declspec(dllexport)} and imported with
@code{__declspec(dllimport)}. If this macro is not used, libtool will
assume that the package libraries are not dll clean and will build only
static libraries on win32 hosts.
@code{AM_PROG_LIBTOOL} must be called @strong{after} this macro, and
provision must be made to pass @samp{-no-undefined} to @code{libtool}
in link mode from the package @code{Makefile}. Naturally, passing
@samp{-no-undefined} means that all the library symbols @strong{really are}
defined at link time!
