Hadrian appears not to expand CONF_GCC_SUPPORTS__ATOMICS correctly
Looking at _build/stage1/lib/ghcautoconf.h I see:
/* Does GCC support __atomic primitives? */
#define HAVE_C11_ATOMICS $CONF_GCC_SUPPORTS__ATOMICSThis can't be right.
Due to a large amount of spam we do not allow new users to create repositories, they are "external" users. If you are a new user and want to create a repository, for example for forking GHC, open a new issue on ghc/ghc using the "get-verified" issue template
