Target-specific Variables

[Michael Morrell]

I've just started trying to use target-specific variables and I'm getting 
results I don't understand.  I'm
using make 3.81.

With this Makefile:

============================
a: SRCS = a1.c a2.c

OBJS = $(SRCS:.c=.o)

a: $(OBJS)
        @echo $(OBJS)
        @echo Making $@ from $^
        @touch $@
============================

I get the output:

============================
a1.o a2.o
Making a from
============================

So, OBJS is defined correctly in the rule, but not as a dependency.  What is 
that?
