} This passed me by, and it obviously needs changing, but the awk stuff
} is a bit minimal.
The reason for invoking "make -nsp ..." appears to be to get "include"
lines to be processed, with conditionals like "ifdef" and "ifeq" as a
secondary consideration. The problem seems to be that "make -n" doesn't
really mean what it says -- make will still execute its internal rules
for building other makefiles, even though it won't execute the commands
for building explicit non-makefile targets.
Unfortunately I don't see any reasonable workaround. I toyed with a
little function to do simple "include" processing, but it chokes when
the include line mentions a make variable (such as $(ARCH) in the linux
sources). It might be possible to write something that emulates make
to the extent of being able to deal with this, but even in Perl I'm not
too keen on attempting it.
So we may be stuck with the awk we have, except that we could unfold any
backslash-continued lines before awking. That'd be as easy as adding a
"while read -e; do : done" to the command substitution.
(Or at least I though it would, but:
zsh% while read -e; do :; done < Makefile | less
hangs until interrupted. This works:
zsh% { while read -e; do :; done < Makefile } | less
What's up with that first one?)
