-Date: Sun, 22 Sep 2019 23:04:48 +0000
-Subject: [PATCH] fix gthr weak refs for libgcc
-
-ideally gthr-posix.h should be fixed not to use weak refs for
-single thread detection by default since that's unsafe.
-
-currently we have to opt out explicitly from the unsafe behaviour
-in the configure machinery of each target lib that uses gthr and
-musl missed libgcc previously.

-Subject: [PATCH] fix gthr weak refs for libgcc
-
-ideally gthr-posix.h should be fixed not to use weak refs for
-single thread detection by default since that's unsafe.
-
-currently we have to opt out explicitly from the unsafe behaviour
-in the configure machinery of each target lib that uses gthr and
-musl missed libgcc previously.
