The same pattern appears (for the Rosenbrock function) in the Tcl version, but
I have no idea what it is supposed to draw and why the Fortran version does not
show this. All the calls are there in all versions. Really odd. If anyone has
fresh ideas where to look for the discrepancy, I'd be obliged.

There is something extremely weird going on with the make utility that comes
with MinGW, but the workaround is to use "mingw32-make" instead of "make".
Cygwin gives nice clean results using "make test_noninteractive", except for
example 8 (see above). Under MinGW I do not have the test scripts, which is odd
(I have not investigated this point yet). Therefore I checked example 8
manually: the same result as under Cygwin.
All the testing indicates that apart from the oddities in example 8 everything
is working fine. I will check with the sombrero function.
Another curiosity about MinGW: it seems the symbols are exported automatically,
just as in Cygwin and Linux. No need for the "definitions file" (.def) anymore.
This seems a change from previous versions.

Arjen
PS I will be on a week's holiday from Saturday onwards. Not sure how much I can
do until that time.
