From bb109fb6bc458b93cdc29c2e597efb8331e94ca1 Mon Sep 17 00:00:00 2001 From: Michael Jeanson Date: Fri, 23 Nov 2018 15:27:04 -0500 Subject: [PATCH] Fix: compat_futex_noasync on Cygwin The futex_noasync compat code uses a weak symbol to share state across different shared object which is not possible on Windows with the Portable Executable format. Use the async compat code for both cases.
