-Subject: [PATCH] libcody: Make it buildable by C++11 to C++26
-
-The following builds with -std=c++11 and c++14 and c++17 and c++20 and c++23
-and c++26.
-
-I see the u8 string literals are mixed e.g. with strerror, so in
--fexec-charset=IBM1047 there will still be garbage, so am not 100% sure if
-the u8 literals everywhere are worth it either.
-
-2025-11-21 Jakub Jelinek <jakub@redhat.com>
-
- * cody.hh (S2C): For __cpp_char8_t >= 201811 use char8_t instead of
- char in argument type.
- (MessageBuffer::Space): Revert 2025-11-15 change.
- (MessageBuffer::Append): For __cpp_char8_t >= 201811 add overload
- with char8_t const * type of first argument.
- (Packet::Packet): Similarly for first argument.
- * client.cc (CommunicationError, Client::ProcessResponse,
- Client::Connect, ConnectResponse, PathnameResponse, OKResponse,
- IncludeTranslateResponse): Cast u8 string literals to (const char *)
- where needed.
- * server.cc (Server::ProcessRequests, ConnectRequest): Likewise.
-
-(cherry picked from commit 07a767c7a50d1daae8ef7d4aba73fe53ad40c0b7)
