The attached fortran code (a smaller section cut and paste from original) was generated by a custom preprocessor. The code very much seems to be valid fortran 77, though its has some weird tab spacings; It compiles (and executes) fine with pgf90 and ifort-8.x. The compile time error is as below (same with gfortran-4.1.2, 4.2 and 4.3.0 trunck build);
