Interesting, I have been doing -j16, -j14, and -j2 builds and have not
hit this.

  I just started seeing this, with "make -j4":

  There is indeed no rule to make classpath/lib/compile-classes, as it's
generated in a recursive sub-make (which would happen earlier in a
non-parallel build, or at lower -j levels, rather than simultaneously and
racily as here).  Presumably we need to add some dependency at the top level,
perhaps something like this?

classpath/lib/compile-classes: all-multi

  Hm.  Maybe I've broken something with a local modification.  I'll try it
from a clean tree and see if it happens there.  Maybe I messed it up by adding
a dependency to the top-level "all:".  Thanks for the all-clear report.

I also do builds using -j9 and haven't seen such issues, but this is
on x86_64-pc-linux-gnu rather than cygwin.

  Nah, sorry for the noise.  I definitely went about adding a dependency
wrongly, with the result of dragging half the recursive dependencies up to the
top-level.  I think I want to append to "all-am:", not "all:", and most
probably the simplest way to do that validly is to add the phony stamp file
target to noinst_DATA.
