speaking of which, what do you do when you hit this limit? I have a
makefile that builds a huge list of filenames, then selects subsets of
this list for various purposes, ie:

ALLFILES:=$(shell find -type f)
CFILES:=$(filter %.c, $(ALLFILES))
JAVAFILES:=$(filter %.java, $(ALLFILES))

I've found this to be faster than running multiple find commands.

However, on this project, ALLFILES has grown to the point where it no
longer fits on a single command line. I can't do this, for example:

allfiles.list: $(ALLFILES)
        echo $(ALLFILES) | tr ' ' '\n' > $@

because that command is just too big.

What's the best workaround for this in GNU make?
