+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

++ In the ideal case, the length of each bucket is roughly the number of

++ yielding shorter chains, *given* the `hasher' function behaves properly.

++ sizes in hope to reduce the average length of buckets, but this might
++ become inordinate, as unused slots in the hash table take some space. The
