This means that when you are installing your new data type, there is
already a preferred assignment conversion for assignments of matrix to
unknown type and you are replacing it with a new definition.

Likewise, this means that when you are installing your new data type,
there is already a widening op for converting a fixed scalar to a
fixed matrix and you are replacing it with a new definition.

Yes, these warnings were added recently.  But other than that, the
code in ov-typeinfo.cc has not changed.  So with earlier versions,
Octave was failing to tell you about a potential problem.
