on cygwin both 32 and 64 bit I see
netdb.h:#define NI_NAMEREQD 0x4 /* Not being able to resolve is
an error. */
same on
w32api/ws2tcpip.h:#define NI_NAMEREQD 0x04
curiosly I see also on
roken-common.h:#define NI_NAMEREQD 0x02
$ cygcheck -f /usr/include/roken-common.h
libkrb5-devel-1.5.3-1
not sure if it has any relevance at all in this case.
