Subject: [PATCH] libstdc++: Export the __gnu_cxx::zoneinfo_dir_override symbol.
Date: Sat, 24 Dec 2022 11:35:25 +0000 [thread overview]
Message-ID: <20221224113525.20201-1-iain@sandoe.co.uk> (raw)
If this is not the right place to export the symbol (or you do not want
to export it in the general case), I can always add a platform-specific
file for it. So far, tested on x86_64-darwin21, wider testing will
follow over the holidays.
OK for trunk?
Iain

This symbol needs to be visible in the library interface for Darwin
to override it with a user-provided one.
