From 9406d93e77e7923e2788e43df50cf3a577f1c42b Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Tue, 21 May 2019 10:06:06 +0200 Subject: configure: detect getsockname and getpeername on windows too Made detection macros for these two functions in the same style as other functions possibly in winsock in the hope this will work better to detect these functions when cross-compiling for Windows.
