Checking the buildfarm to see if ed9b3606d broke anything, I notice
that woodlouse is producing stacks of warnings like this:
src/port/thread.c(134): warning C4996: 'gethostbyname': Use getaddrinfo() or GetAddrInfoW() instead or define
_WINSOCK_DEPRECATED_NO_WARNINGSto disable deprecated API warnings
[C:\buildfarm\buildenv\HEAD\pgsql.build\libpgport.vcxproj] C:\Program Files (x86)\Windows
Kits\8.1\Include\um\winsock2.h(2238): see declaration of 'gethostbyname'
and was doing so before that commit, so it's not my fault :-)
win32.h has
* Also for VS2015, add a define that stops compiler complaints about* using the old Winsock API.*/
#if defined(_MSC_VER) && _MSC_VER >= 1900
#define _WINSOCK_DEPRECATED_NO_WARNINGS
but evidently it chose the wrong cutoff for when to enable that
symbol, because woodlouse is (or claims to be) running VS2013.
Is there any good reason not to just define
_WINSOCK_DEPRECATED_NO_WARNINGS unconditionally? Presumably
it would have no effect on VS versions too old to know the symbol.
I'm a bit inclined to move it to win32_port.h, as well,
since that's what includes <winsock2.h>.
