• g77 treats constants like `Z'ABCD'' and `'ABCD'Z' as typeless. It seems like maybe the prefix-letter form, `Z'ABCD'', should be `INTEGER' instead. You can test for yourself whether a particular compiler treats the prefix form as `INTEGER' or typeless by running the following program:

  EQUIVALENCE (I, R)
  R = Z'ABCD'
  J = Z'ABCD'
  IF (J .EQ. I) PRINT *, 'Prefix form is TYPELESS'
  IF (J .NE. I) PRINT *, 'Prefix form is INTEGER'
  END
  

  If you wish to report the results of this test to the maintainers of g77, please include full information on the compiler, system, and version information you're using. (We already know how g77 handles it, of course.) Perhaps this will be changed in version 0.6.
• `LOC()' and other intrinsics are probably somewhat misclassified. Is the a need for more precise classification of intrinsics, and if so, what are the appropriate groupings? Is there a need to individually enable/disable/delete/hide intrinsics from the command line?
