Is the MapServer code supposed to be ANSI C?

You might be correct (I do not know the code in question well enough
to know if this index might end up above 128), but I would consider it
dangerous to change the type to a wider one, as it should change the
size of the structure and break compiled programs linked against
libmap.

You are right, almost all other index types are 'int', with the
possible exception of tileindex in layerObj.
