+Subject: [PATCH 2/3] Fix build with musl libc
+
+On musl libc the fopen64 and fopen are the same thing, but for
+compatibility they have a `#define fopen64 fopen`. Same applies for
+fseek64, fstat64, fstatvfs64, ftello64, lstat64, stat64 and tmpfile64.

+Subject: [PATCH] SCC: Allow ReplaceNode to safely support insertion
+
+If scc_iterator::ReplaceNode is inserting a new entry in the map,
+rather than replacing an existing entry, the possibility of growing
+the map could cause a failure. This change safely implements the
+insertion.
