1.11 Libtool and Windows
========================
If you want it to be possible to cross-compile your program to MinGW
and you use Libtool, you need to put:
AC_LIBTOOL_WIN32_DLL
in your `configure.ac'.
The effect of this is that the names of the `OBJDUMP', `DLLTOOL',
and `AS' tools are set up correct.
If you are building a library, you will also need to pass
`-no-undefined' to make sure Libtool produce a DLL for your library.
>From a `Makefile.am':
libgsasl_la_LDFLAGS += -no-undefined
