I tried to resurrect your patch, but it partly misses on the following:

      integer, parameter :: ck = kind ("a")  ! default character kind
      print *, ck_"a"
      print *, ck _"a"
      print *, ck_ "a"
      print *, 1_"a"
      print *, 1 _"a"
      print *, 1_ "a"
      end

pr92805.f90:3:19:

    3 |       print *, ck _"a"
      |                   1
Error: Syntax error in PRINT statement at (1)
pr92805.f90:4:20:

    4 |       print *, ck_ "a"
      |                    1
Error: Syntax error in PRINT statement at (1)

For some reason we detect only some of the syntax violations.
