I assumed i was an integer. F95 says:

Constraint: If the optional characters FMT= are omitted from the format
specifier, the format
specifier shall be the second item in the control information list and the
first item shall be
the unit specifier without the optional characters UNIT=.

The formulation of F2003/2008 is les explicit, but probably says the same
thing:

C918 (R913) If format appears without a preceding FMT=, it shall be the second
item in the io-control-spec-list and the first item shall be io-unit.

So I think gfortran is right to reject (unit=2, 100), it should be (2, 100) or
(unit=2, fmt=100).
