+Subject: [PATCH] Unset need_charset_alias when building for musl
+
+localcharset uses ac_cv_gnu_library_2_1 from glibc21.m4
+which actually shoudl be fixed in gnulib and then all downstream
+projects will get it eventually. For now we apply the fix to
+coreutils

++   function, or just `hasher' for short) into a number (or `slot') between 0
++   and the current table size.  At each slot position in the hash table,
++   starts a linked chain of entries for which the user data all hash to this
