That's clear.
The evil m4 hackery comes from the way that the files are generated.
The file name is passed to m4, which is then parsed with the macros
in libgfortran/m4/iparm.m4 , where (among other things) 'i' in the
name of the file to be generated is translated to GFC_INTEGER_...
in the macros rtype, rtype_name and rtype_code (if that exists).
So, I will need to either persudade iparm.m4 to check for the
matmul name and redefine the get_typename macro accordingly, or
(probably the easier option) to redefine rtype and friends
if rtype_name happens to match ^GFC_INTEGER, in matmul.m4.
