On a second though, by double-checking the existing code, I couldn't see how
the 'cygnus' option could possibly influence the location of the generated
info files -- and it turned out it didn't!  Despite what was documented in
the manual, the 'cygnus' option did *not* cause the generated '.info' files
to be placed in the builddir (see attached test case).  This is true for at
least for automake 1.9.6, 1.10.3, 1.11.1, 1.11.4, and automake built from
the master branch (I've checked them all).  Since nobody ever complained
about such a breakage, I conclude that the feature was not truly needed, and
I'm thus withdrawing my previous patch.

Regards,
  Stefano
