Avoid mixing void and integer in a conditional expression.
The C standard says that the second and third arguments of aconditional operator shall be both void type or both not-voidtype. The Windows version of INTERRUPTS_PENDING_CONDITION()got this wrong. It's pretty harmless because the result ofthe operator is ignored anyway, but apparently recent versionsof MSVC have started issuing a warning about it. Silence thewarning by casting the dummy zero to void.Reported-by: Christian Ullrich <chris@chrullrich.net>Author: Bryan Green <dbryan.green@gmail.com>Reviewed-by: Tom Lane <tgl@sss.pgh.pa.us>Discussion:https://postgr.es/m/cc4ef8db-f8dc-4347-8a22-e7ebf44c0308@chrullrich.netBackpatch-through: 13
