When support ended for g77 I feared for my collection of old fortran 
code, but it all worked fine under gfortran after a few trivial changes 
that I made years ago. (BLOCK DATA had to be rewritten, but I had used 
that only once.) The gfortran developers must intend to keep viable all 
that netlib code that has been widely used and thoroughly debugged. No 
problems with the above gfortran version, which is newer than the most 
recent one for Cygwin. So I doubt that the error message comes from 
intentional compiler changes.

Like you, I can't understand why a syntax error should appear at run 
time.  gfortran is good at finding syntax errors at compile time.

I'm still using fortran 77 because it meets my needs, I know where the 
bugs hide, and that is the language of most netlib code and of all my 
old tools. gfortran handles it well.
