That's got it. Thanks.

I tried it, and get the results I hoped for.
I guess that, for the other Makefile.in files, I'll have to do something
similar. Do you know of a guide to the expansion rules for the standard
macros (eg. @libexecdir@ -> @exec_prefix@/libexec, @exec_prefix@ -> @prefix@,
etc.)? I guess that I dig through config.log for the expansions, and
retro-fit them into my Makefile.in, if necessary.
