Subject: [PATCH] libgcov: Fix build on Darwin [PR99406]
Date: Fri, 5 Mar 2021 15:00:19 +0100 [thread overview]
Message-ID: <20210305140019.GI745611@tucnak> (raw)
Hi!
As reported, bootstrap currently fails on older Darwin because MAP_ANONYMOUS
is not defined.
The following is what gcc/system.h does, so I think it should work for
libgcov.
Build tested on x86_64-linux, ok for trunk?

* libgcov.h (MAP_FAILED, MAP_ANONYMOUS): If HAVE_SYS_MMAN_H is
defined, define these macros if not defined already.
