You just answered your own question: "b" & "c" depend on "a", so make "a"
a dependency for "b" & "c":
all: a b c
a:
b: a
c: a
For more tip's on parallelizing makefiles, see my paper "GNU & You, Building
a Better World"
published in the Proceedings of the Ninth Annual Sun Users Group Conference,
December 1991.
(The title is a play on "make world" which I had been repeatedly been doing
while compiling X11, and getting really really sick of imake. I completely
ripped imake out of the X11 source tree and replaced everything with
parallel gmake rules.)
