[cygnus.egcs.patches] Re: make -j patch -- part 1 all targets [gcc/Makefile.in]

Well, here's why the ansi2knr stuff didn't work.
Curious that I didn't remember this.  Or run across it before.

I think it must be because we've moved a lot more of the variables
into the *.am files.  In the past we generated a lot of variables in
automake itself.  Automake put all the variables before all the
targets, whereas the new *.am reader does not.

We probably ought to fix the new reader to do this.

In dependency lines, it does.  Compare

FOO = bar
foo: $(FOO)
        @echo foo

and

foo: $(FOO)
        @echo foo
FOO = bar

$ make -f test.mk
make: *** No rule to make target `bar', needed by `foo'.  Stop.
$ make -f test2.mk
foo
