"$<" does not seem to work.  Perhaps this is not implemented in sun's
make, at least not the version you have?

no comment :)



Slightly off topic (not rrdtool specific):

Using "$<" is nice for example for *.c files which include *.h files:

target:   source.c include.h
     $(CC) $< -o $@

Here you want to rebuild target if source.c changed and/or if include.h
changed, but you only want to list source.c on the command line for cc.

target:   source.c include.h
     $(CC) $< -o $@

would result in "cc source.c -o target"

whereas 

target:   source.c include.h
     $(CC) $^ -o $@

would result in "cc source.c include.h -o target"
