--- Comment #16 from Arjen Markus <arjen.markus895 at gmail dot com> --- To get more involved in gfortran, I thought this issue might be a good starting point (it is the first of a number that Steve Kargl posted some time ago for this purpose). I added a small test program to check for the support of all integer kinds for the various legacy routines. The issue has already been solved for kill, but not yet for the other routines mentioned here.
