I think the key issue here is that there is no compiler in use anymore that *only* supports F77 syntax (even those that have "77" in their executable name).  There hasn't been a only-supports-fortran-77-syntax compiler for many, many years (since the early-/mid-90s? That's a guess).

So using (KIND=foo) syntax, even though that didn't debut until F90 or F95 (or whatever; I'm no Fortran expert) is perfectly acceptable here.
