You shouldn't rely on configure.scan (generated by autoscan). Not only does
it underquote the macros, but usually doesn't respect the autoconf manual
guidelines.
You should rely more on the libtool, autoconf and automake manuals, which
are of great help to create a 'portable' configuration for a package.

The libtool manuals states that AC_PROG_LIBTOOL *must* be called before
AC_PROG_LIBTOOL.

AFAIK, AC_ENABLE_SHARED and AC_ENABLE_STATIC aren't usefull in this case
since LIBTOOL will always try to create shared and static libraries. Of the
other hand, if you wish to use AC_DISABLE_SHARED or AC_DISABLE_STATIC, they
too must be called before AC_PROG_LIBTOOL.

Also, avoid underquoted (ie. the AC_INIT you used) and deprecated (ie.
AM_INIT_AUTOMAKE(PACKAGE, VERSION) macros. Spaces do count when in between
brakets, this can cause painful to find bugs in the configure scripts.

Reorganized, your configure.ac should rather be :
AC_INIT([Test],[0.1])
AC_CONFIG_SRCDIR([Dll.h])
AC_CANONICAL_SYSTEM
AM_INIT_AUTOMAKE
AC_PROG_CC
AC_PROG_CXX
AC_LIBTOOL_WIN32_DLL
AC_PROG_LIBTOOL
AC_CONFIG_FILES([Makefile])
AC_OUTPUT

I'm not sure of what AC_LIBTOOL_SETUP does, so I didn't include it. As for
AC_INSTALL, you should rather use AC_PROG_INSTALL, but at least
AM_INIT_AUTOMAKE or AC_CONFIG_SRCDIR check for /bin/install or install-sh

You must also set `libtest_la_LDFLAGS = --no-undefined'
You might also want to add versioning to libtest_la_LDFLAGS with either
`--version x:y:z' or `--release x' (view libtool manual for more precise
information) It's this versioning information that adds the version number
to the dll.
`hello' should rather use `hello_LDADD = libTest.la' instead of
`hello_LDFLAGS = libTest.la'

A plain `autoreconf' (or autoreconf -i) would do the trick.

Answered just above ;-)

Hope it helps,
