+# GCC 8 — legacy version for old-vendored-C++ projects.
+#
+# Many projects vendoring older C++ libraries (RocksDB 6.3.x, old
+# MySQL 5.7, old InnoDB, pre-C++17 codebases generally) hit the
+# stricter copy-ctor / atomic / pair-construction rules introduced
+# in gcc 12+ libstdc++. They compile cleanly with gcc 8 which was
+# the last major to default to C++14 / gnu++14 ABI.
+#
+# Companion to gnu.org/gcc (latest) for cubefs.io, mysql.com/v5_7,
+# and other from-source recipes that can't easily be patched to
+# modern C++.

+# MySQL 5.7 — legacy line.

+# 5.7 reached EOL in October 2023 — homebrew dropped its `mysql@5.7`
+# formula in 2024. Some legacy applications (Rails 5.x apps,
+# WordPress legacy sites, custom replication setups) still pin to
+# 5.7 because the 8.0 migration broke their schema or auth modes.
+#
+# Build is best-effort — 5.7 needs older C++ idioms, boost 1.59,
+# OpenSSL 1.0.x patterns. Expect to iterate.

+# Closes part of pkgxdev/pantry#99 (Top 300 holdout #735).
