I got it now, Paul. I'm building under cygwin and that environment provides an
opportunity for some inconsistencies in path names, namely that a path can be,
e.g., either "s:/mypath/..." or "/cygdrive/s/mypath/...". That confusion plus
a missing rule was causing my problems. Thanks for your help, which, even
thought wasn't directly applicable, helped isolate the real problem.
