OK: a CygWin update followed by "mv acsite.m4 aclocal.m4" fixed it for me. Details
below.

The autogen.sh adds "-I ." only for Irix. That souns a bit suspicious because I used
to have to use it in CygWin, so I tried it just now, but it didn't make any difference
to my present problem. I guess it's needed for some versions of the autotools but not
others.
Then I updated my CygWin autotools to the latest, because although my older versions
had been working OK I thought I might have an inconsistent set of different packages.
This led to different errors, and since the CygWin installer doesn't let me return to
earlier versions even though I still have the package files locally, I had to continue.

Eventually I remembered that Ross Golder had found that "mv acsite.m4 acinclude.m4"
worked for him. I already had an acinclude.m4 which was identical to my acsite.m4, so
the only effect of this command was to delete acsite.m4. But it worked! I wish I
understood this magic.
