if you want to build dll on windows with msys/mingw you either *have to*:

1) use AC_PROG_LIBTOOL and call AC_LIBTOOL_WIN32_DLL before and add 
-no-undefined to libtool flag in the Makefile.am that build the library. 
This way is considered deprecated since 2004-02-20 (in automake 1.9b).

2) or use LT_INIT([win32-dll]) and add -no-undefined to libtool flag in 
the Makefile.am that build the library. LT_INIT was introduced after 
libtool > 1.5.

As poppler development has certainly begun after 2004 (poppler 0.2 was 
released in 2005, there is no date for 0.1), I think that you can safely 
use the new libtool calls.
