is_notpadded is a member of the unit_flags struct, but it's never set nor used: ~/gcc $ grep -r is_notpadded libgfortran/ libgfortran/io/io.h: int is_notpadded; How was it supposed to be used? I guess it has been here for a long time, since g95 does have the same definition (and does not use it either). Does anyone have an objection to my removing it? FX
