Implementing soname versioning (at least for Linux) is simple enough;
just add:

	-Wl,-soname,$(SONAME)

to the linking command for building shared libraries, where $(SONAME)
is the library name, e.g.:

	SONAME = $(SHLIB_PREFIX)$(SHLIB_NAME)$(SHLIB_SUFFIX).$(SHLIB_VERSION)

[SHLIB_VERSION would need to be defined in any Makefile which includes
Lib.make.]

The main problem is ensuring that developers actually increment the
version whenever they make an incompatible change (otherwise there is
no point in having versioning).
