Subject: Work around GCC -Wunused-result

(cf. <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66425> "(void) cast doesn't
suppress __attribute__((warn_unused_result))").  Interestingly, this only occurs
with GCC 7, look like <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70365>
"warn_unused_result doesn't warn when the result is a class with a destructor"
is fixed now.
