If you specify the option '--enable-dl' or '--enable-dl=yes', which both
are equivalent to '--enable-dl=ltdl', it is assumed that the GNU Libtool
(see http://www.gnu.org/software/libtool/ ) is installed on your system.
You also can specify '--enable-dl=dlfcn', in which case the Posix
version of the dynamic linking will be used rather than the GNU Libtool.
However, using the GNU Libtool is preferable in most cases.

On Windows the dll name looks like 'glpk_4_30.dll' to avoid linking to
a wrong version of the library.
