Dear Mr. Eaton,
thank you for your comment. In my case:
echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin

/usr/bin/gnuplot

        G N U P L O T
        Version 4.0 patchlevel 0
        last modified Thu Apr 15 14:44:22 CEST 2004
        System: CYGWIN_NT-5.0 1.5.11(0.116/4/2)

So: there is gnuplot, there is PATH pointing to the location where gnuplot =
resides. However, configure defaults to pgnuplot -> there must be something=
 wrong.

Therefore I made 2 different tests:
1.) run ./configure "as is":
./configure --prefix=3D/usr > logfile 2>&1 results:
*****
checking whether ln -s works... yes
checking for nm... (cached) nm
checking for runtest... runtest
checking for a BSD-compatible install... /usr/bin/install -c
checking for pgnuplot... pgnuplot
checking to see if your gnuplot supports multiplot... no
checking to see if your gnuplot supports multiple plot windows... no
checking for less... less
checking for gperf... gperf
*****
2.) modify ./configure by commenting out GNUPLOT_BINARY=3D"$gp_default":
19389c19389
< GNUPLOT_BINARY=3D"$gp_default"
---
> # GNUPLOT_BINARY=3D"$gp_default"

./configure --prefix=3D/usr > logfile 2>&1 results:
****
checking whether ln -s works... yes
checking for nm... (cached) nm
checking for runtest... runtest
checking for a BSD-compatible install... /usr/bin/install -c
checking for pgnuplot... no
checking for pipe-gnuplot... no
checking for gnuplot... gnuplot
checking to see if your gnuplot supports multiplot... yes
checking to see if your gnuplot supports multiple plot windows... yes
checking for less... less
checking for gperf... gperf
****

So: the configure provided with the sources does actually not check for gnu=
plot if GNUPLOT_BINARY remains defined. This has been the root cause of my =
issue, I erratically pointed you to aclocal.m4 what I did not use to create=
 the configure - script. Therefore I cannot really say whether this is a co=
nfigure problem or an aclocal.m4-problem, too.
Moreover, there is a line in configure saying: (19407)
  if test -n "$GNUPLOT_BINARY"; then
  ac_cv_prog_GNUPLOT_BINARY=3D"$GNUPLOT_BINARY" # Let the user override the=
 test.
This seems to be the reason for this to me.


Many thanks for your ongoing support,
take care

I think what is supposed to happen is that on Cygwin systems,
configure will check for pgnuplot, pipe-gnuplot, then gnuplot, in that
