3 ! Emit a diagnostic for too small PUT array at compile time
6 ! Possible improvement:
7 ! Provide a separate testcase for systems that support REAL(16),
8 ! to test the minimum size of 12 (instead of 8).
10 ! Updated to check for arrays of unexpected size,
11 ! this also works for -fdefault-integer-8.
