+Subject: [PATCH] custom allocators: define missing 'rebind' type
+
+`gcc-13` added an assert to standard headers to make sure custom
+allocators have intended implementation of rebind type instead
+of inherited rebind. gcc change:
+    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=64c986b49558a7
+
+Without the fix build fails on this week's `gcc-13` as:

+The change adds trivial `rebind` definition with expected return type
+and satisfies conversion requirements.
