   PR libfortran/28005
   * m4/matmul.m4: aystride = 1 does not uniquely detect the
   presence of a temporary transpose; an array element in the
   first dimension produces the same signature.  Detect this
   using the rank of a and add specific code.

I'll review it today (in the next 12 hours, for those not in the Parisian timezone). I just need to take a pen a write the diagram to convince myself that it's doing the right thing, but I need some strong breakfast first ;-)
