Thanks for the bug reports.

This warning is safe to ignore for the moment -- it is there because
we don't have a function to return a "const column" or "const row" in
GSL so I have just used the non-const version of the function.  It is
something which I will be fixing shortly.

The failures involved denormalized numbers, which have been rounded to
zero.  Presumably denormalized numbers are not supported by that
architecture (looking at the comments in ieee-utils/fp-irix.c suggests
this).  If they are not supported then we can modify the test program
to avoid looking at them.
