If you try to use automake-1.5 when building with the autoconf system,
you may have to apply below patch to the automake-1.5 source if you get
errors about .dep/*.Po files which can not be made, or target_hooks which
are not defined. These are two known error which are partly triggered 
because we do not call our makefiles Makefile (but use GNUmakefile instead). 
The simple patch is included below. Autmake-1.5d and later should not need
this.
