+Subject: [PATCH] PythonAllocator: 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:

+| ../recipe-sysroot/usr/include/c++/13.0.1/bits/alloc_traits.h:70:31: note: 'std::integral_constant<bool, false>::value' evaluates to false
+
+The change adds trivial `rebind` definition with expected return type
+and satisfies conversion requirements.
