Default value for option -std for c and c++

[lijh8]

Clangd version: Apple clangd version 14.0.0 (clang-1400.0.29.202); clangd extension version: v0.1.29; Operating system: macOS 12.7.6;

I happen to encounter this problem. Both the compile_commands.json and compile_flags.txt examples do not include the option -std=, failing to have this option in these two files results in the -I/path/to/header to be ignored. This also causes problem in .clangd and the clangd.fallbackFlags of vscode settings.json.

But the option -std do have default value, so we do not have to specify this in our Makefiles.

compile_commands.json without `-std`

{ "directory": "/Users/ljh/Documents/lijh8.github/Asio/src/main/", "arguments": [ "/usr/bin/clang++", "-DSOMEDEF=With spaces, quotes and \\-es.", "-I/Users/ljh/Downloads/asio-1.30.2/include", "-c", "-o", "server.o", "server.cpp" ], "file": "server.cpp" },

log without `-std`
