[ADOL-C] Problems installing cygwin

[bradbell at seanet.com]

When I try to install adolc, using the command
    autoreconf -f -i
which seems to be necessary if one has the autotools installed, I get the
message

configure.ac:44: error: possibly undefined macro: AC_LIBTOOL_WIN32_DLL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure.ac:45: error: possibly undefined macro: AC_PROG_LIBTOOL
autoreconf-2.68: /usr/bin/autoconf-2.68 failed with exit status: 1

This is very similar to the discussion

But the solution "Version 2.3.0 seems to have removed this difficulty."
does not work for me; i.e., I am using ADOL-C-2.3.0.
