 # Libtool supports a --disable-shared option to tell it to avoid

 # building shared versions of libraries. We don't have any libraries

 # but we do want to support building static versions of our executables.

 # Libtool can do this (under the right circumstances) so we overload

 # this switch for this purpose.

 #

 # The libtool option that we use (-static-libtool-libs) means to use

 # static linking with libraries that supply a .la file and which

 # include a non-empty value for "old_library". If the library doesn't

 # include a .la file (they are deleted by some distributions), then

 # this option will have no effect and likewise if old_library is set

 # to '' (eg., if the library was build with --disable-static) then

 # again -static-libtool-libs will have no effect.

 #

 # If old_library is set to a non-empty value, then specifying

 # -static-libtool-libs will cause the link to fail if the old library

 # cannot be found (libtool will not fallback to a shared library

 # in these circumstances). This can happen with Fedora, for example,

 # if a main mingw32 library package is installed but not the

 # coresponding static sub-package. The solution is to either

 # install the relevant static sub-packages or don't use --disable-shared.
