The output of "install-info --version" is:

   install-info (GNU texinfo) 4.13

That was the cause.  Changing my configure command to use
"--prefix /c/apps/emacs" fixes the problem on my Windows machine.
It appears that version 4.13 of MinGW/MSYS install-info is confused
by the drive letter in the pathname.  I'll pursue this with the MinGW
folks.
