[PATCH] DLL support on cygwin

Hi,

I made a small patch to allow to build libaudiofile as DLL on Cygwin.

Changes: 
* configure.in: call AM_PROG_LIBTOOL after AC_PROG_CC.
* configure.in: call AC_LIBTOOL_WIN32_DLL.
* libaudiofile/Makefile.am (libaudiofile_la_LDFLAGS): add -no-undefined.

Hope this is of use/interest,
