Details:

tmac/doc.tmac-u says the following:


  64 .\" Load start-up files
  65 .ie t \
  66 .  mso mdoc/doc-ditroff
  67 .el \
  68 .  mso mdoc/doc-nroff
  69 .
  70 .mso mdoc/doc-common
  71 .mso mdoc/doc-syms


...but these references don't resolve even after the tree is built.  They only
work after installation somewhere else.  Even test-groff(.in), which sets
GROFF_TMAC_PATH, is no help because these msos demand a directory called
mdoc.

A workaround would be for the build process to make a symlink in tmac called
mdoc which points back to ".", and have the clean rule get rid of that
symlink.

Any better ideas?

If not, I'll see if I can figure out how to persuade Automake to do what I
want.
