Compilation of the attached F90 module which uses liked lists, causes the
following error message to
appear repeatedly. removing the use of => null() to initialise the pointers
causes comilation to suceed.
The code compiles sucesfully under compac visual fortran on a PC and Pro
Fortran on an SGI system.
The output from "gfortran -v -save-temps -c CutCellRoutines.f90" is
Using built-in specs.
