X-Git-Tag: REL_16_BETA1~2204 X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=c290e79cf07f5784fd68e726177503a6805c28d6;p=postgresql.git windows: msvc: Define STDIN/OUT/ERR_FILENO. Because they are not available we've used _fileno(stdin) in some places, but that doesn't reliably work, because stdin might be closed. This is the prerequisite of the subsequent commit, fixing a failure introduced in 76e38b37a5.
