You shouldn't be able to compile this without fixing the incompatible mixture 
of fixed and free format input.  My cygwin g77 versions had no difficulty 
with this, when I used binary/unix files, and fixed the source code format.  
I still wouldn't trust libf2c I/O library to read DOS text format files, and 
I can't tell if that was what you wished to do.
