In the current GRASS-5.7-CVS (ours) it is implemented like this:

ls -la $GISBASE/lib | grep libgrass_gis
-rwxr-xr-x 1 neteler  ssi 799574 Dec 2 14:19 libgrass_gis.5.7.cvs.so
lrwxrwxrwx 1 neteler  ssi     23 Dec 2 14:19 libgrass_gis.so -> libgrass_gis.5.7.cvs.so

The rule is here:
 include/Make/Shlib.make

$(SHLIB): $(SHLIB_OBJS)
        $(SHLIB_LD) -o $@ $(LDFLAGS) $^ $(EXTRA_LIBS) && ln -sf $(notdir $@) $(patsubst %.$(GRASS_VE
RSION_NUMBER)$(SHLIB_SUFFIX),%$(SHLIB_SUFFIX),$@)

Please suggest for changes (or, Hamish may do it in CVS).
