Thanks. I got the latest CVS and verified this. But now I have a new 
oddness:

x=hello

david.a.b: x=david

%.b: x+=a

%.a.b: x+=a+b

david.a.b: x+=c

david.a.b:
        @echo $(x)

3.80 gives "hello a david c"
cvs gives "hello a a+b david c"

Neither of those seem correct. What are the rules for mixing pattern 
specific variables and target specific variables?
