Target-specific variables

[Asperheim, Eric]

All,

Does anyone know if "Target-specific variables" are supported in gmake
version 3.74-96q4?

fhi2009:easperhe gmake -v
GNU Make version 3.74-96q4, by Richard Stallman and Roland McGrath.

I'm trying to use target-specific variables and it doesn't seem to be
working. I'm using the exact example from the gmake 3.79.1 documentation
(the latest):

prog : CFLAGS = -g
prog : prog.o foo.o bar.o
        @echo $(CFLAGS)

When I type "gmake prog", I get the following 

fhi2009:easperhe gmake prog
gmake: *** No rule to make target `CFLAGS', needed by `prog'.  Stop.

What am I doing wrong if it's not the version? If it is the version, how can
I get a list of features and it which version the feature was added? 

Thanks,

Eric
