Mathias, I'm not sure I understand your excitement here.  ;)  What 
ultimately has to happen if lib2 depends on lib1 is that the command 
line used to link lib2 mentions lib1 to link against (e.g., something 
like "-llib1" on Unix).

With our current approach, this is a two-level mechanism, where some 
makefile.mk contains a line SHL2STDLIBS+=$(LIB1LIB) and additionally 
some build.lst contains the corresponding module dependency.

Every sane build system that has a global view of things would certainly 
only require this to be a one-level mechanism, where the user-provided 
information that lib2 needs to link against lib1 (the 
"SHL1STDLIBS+=$(LIB1LIB)" part in our current system) is sufficient for 
the build system to automatically derive the corresponding dependencies 
(that lib1 needs to be built before lib2 can be linked).

Or what am I missing?
