to make libtool aware of building a dll:

1) put AC_LIBTOOL_WIN32_DLL before AC_PROG_LIBTOOL (you already did that)
2) add -no-undefined in the *_LDFLAGS cariable in the Makefile.am file
3) have all the dependency dll needed to build the lib.

don't forget to run 'make clean' to force the link again before running 
make.

check if during the link, there is no warning message that tells you that 
libtool can create only the static lib (for some reason). If yes, then the 
dll is not built. Then, paste the message.
