-include fails unexpectedly

[Sankaranarayanan K V]

Hi,

Consider the following Makefile:

--- begin ---
SRCS = a.c a.c

-include $(SRCS:%.c=%.d)

dummy:
        @echo dummy target invoked
--- end ---

'gmake dummy' results in:

gmake: *** No rule to make target `a.d'.  Stop.

How can the repetition of a.c produce this problem?
