Subject: [PATCH 3/4] [gdb/build] Fix struct token_and_value odr violation
Date: Mon, 14 Aug 2023 13:17:20 +0200	[thread overview]
Message-ID: <20230814111721.31402-3-tdevries@suse.de> (raw)
In-Reply-To: <20230814111721.31402-1-tdevries@suse.de>

When build gdb with -O2 -flto I run into:
...
gdb/c-exp.y:3003:8: warning: type 'struct token_and_value' violates the C++ \
  One Definition Rule [-Wodr]
 struct token_and_value
        ^
gdb/d-exp.y:1310:8: note: a different type is defined in another translation \
  unit
 struct token_and_value
        ^
...

Fix this by renaming to c_token_and_value and d_token_and_value.

Likewise in gdb/go-exp.y, renaming to go_token_and_value.

Tested on x86_64-linux.
