And quite a lot earlier, if I recall.

Almost certainly not.  WATFIV had relatively few extensions, and the usual
meanings of "portable Fortran" in such blurb in 1874 were either "standard
Fortran 66" (though with some unavoidable extensions) or the extended subset
accepted by PFORT.

My last remark refers to characters, of course.  PFORT did NOT work on ICL
1900s, at least with some versions of ICL's compilers.
    INTEGER M, N
    DATA M/1H=/,N/1HA/
    M == N
overflowed, for some combinations of character.
