Created April 26, 2024 11:32
From 478902a7e57e2283c57410f5aa14939e743b5102 Mon Sep 17 00:00:00 2001
From: Avi Kivity <avi@scylladb.com>

Subject: [PATCH] antlr3memory.hpp: fix for C++20 mode
gcc 10 in C++20 mode requires that the allocator type match
the type used to allocate, so do that by adding "const" to the
key type.
