Details:

Some compilers run with the `-Wunused-result' flag which tells the compiler to
emit a warning when the result is not used. For example see the warnings here
<https://buildd.debian.org/status/fetch.php?pkg=gnuastro&arch=amd64&ver=0.5-1&stamp=1516267382&raw=0>
for the debian compiler while it was packaging Gnuastro 0.5.

It would be great if these warnings could be removed, both for them selves,
and also so we can spot more important warnings if they pop up.

Éric Thiébaut recently suggested to fix this problem by adding a `(void)'
before the calls to `asprintf'.
