+Subject: [PATCH] Remove -Winline from the list of warnings to use (#95)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+GCC 10 may decline to inline some functions in `alg-yescrypt-opt.c`
+and, with `-Winline -Werror`, this breaks the build.  This warning
+isn’t ever going to expose actual bugs, so let’s just turn it off.
+
+Fixes #95.

+Subject: [PATCH] crypt-common.h: Declare `ascii64` with explicit `extern`.
+
+GCC 10 changes its default compilation mode from `-fcommon` to
+`-fno-common`, which means that tentative definitions of data objects
+will no longer be merged across translation units; instead they will
+produce multiple definition errors.  The `ascii64` constant was
+supposed to be _declared_ in crypt-common.h, but it was accidentally a
+tentative definition instead.  Fix this by adding the `extern`
+annotation that should have always been there.
