Subj : src/xpdev/threadwrap.h To : Git commit to main/sbbs/master From : Rob Swindell Date : Mon Feb 22 2021 05:59 pm https://gitlab.synchro.net/main/sbbs/-/commit/474fa66ed8abaeadbd1e9815 Modified Files: src/xpdev/threadwrap.h Log Message: Gotta define __STDC_NO_ATOMICS__ for MSVC Even though https://docs.microsoft.com/en-us/cpp/preprocessor/predefined-macros?view=msvc-160 says they define it for C compiles, apparently they don't bother for C++. .
