Message-ID: <E1vFbvi-004iJd-0i@gemulon.postgresql.org> (raw)
Avoid mixing void and integer in a conditional expression.
The C standard says that the second and third arguments of a
conditional operator shall be both void type or both not-void
type. The Windows version of INTERRUPTS_PENDING_CONDITION()
got this wrong. It's pretty harmless because the result of
the operator is ignored anyway, but apparently recent versions
of MSVC have started issuing a warning about it. Silence the
warning by casting the dummy zero to void.
