This should hopefully not stop your project from building, but that depends
on other compiler settings.  So if you still get a working executable it's
nothing to worry about (for now).

What's happened here is that Mercury 14.01.1 is fairly old, and uses some
deprecated C compiler flags, on systems with newer C compilers you see noisy
warnings like this.  You can either keep using this version, ignoring these
warnings, or try the ROTD version of Mercury, it's in the same repository
(install mercury-rotd-recommended).  The ROTD version doesn't support 32bit
systems right now.

Good luck.
