But isn't this the correct answer on Irix?  long double is supported
and is equivalent to 'double'.  The C standard allows 'long double'
to be equivalent to 'double'.

The compiler warnings are admittedly annoying, but you can ignore them.

This patch isn't correct, as the two sizes can be equal on conforming
implementations.
