Is it a gfortran bug or a bug in the code ?

f90 code gives a different result for me running 
gcc version 4.3.0 20080428 (Red Hat 4.3.0-8) (GCC)
than the author has posted.

My results:

  Total number of characters =    254
  Reduced number of characters =    170
  The wordsnake score is    264



Is it gfortran or the code ?



       PROGRAM GFORTRAN.ORG
C
C provides information on gfortran 
C
C
C What it is:
C gfortran is the gpl fortran compiler that is part of gcc
C it is a full featured (pretty much) F95 compiler that is
C the replacement for g77.
C
C How to get it:
C
C Check with your OS distributer.  The popular Linux distributions
C all have gfortran available on either the installation media or via
C the update repository. If that fails,check with gfortran wiki
C to obtain binaries for other operating systems.
C And of course source for gfortran is always available for those who like to compile from source.
C
C What happened to g77 ?
C gcc made a major change to internal data structures between gcc3.X and gcc4.X.  No volunteers
C stepped up to transition g77 into the future, while an F95 compiler based on gcc4.X was in work.
C Thus g77 is gone; it is only in versions of gcc.LE.3
C Most g77 code should run under gfortran with minimal or no change.

build g77 from source

C CALL gfortran_for_unix_users
C CALL gfortran_for_windows_users       
C CALL gfortran links       

       END !
