An updated code fragment, old version tsummc00.f, showing the compilation
error.

A smaller code fragment to tsummc001.f which also shows the compilation error.
Here is the output from my test starting with with a version call to gfortran
and ending with an error free compilation when there is no optimization.

[peterm@currawong test]$ gfortran -v

The extensive parameter lists and common blocks are important. They are
normally invoked by the use of include files. The error in in this test also
occurs in a second place in the suite. In both case there are two include
statement lines. In this module everything is okay when only one include
statement is requested. I am searching for other locations in the suite where
there may be two used of include. This is a relatively slow process.
