in OS Monterey

I'm making the #include <> tree in SDK available to another compiler, intel icc

which is identify the SDK include tree and supply it to each icc compile with option -isysroot

% xcrun --show-sdk-path

/Library/Developer/CommandLineTools/SDKs/MacOSX13.1.sdk

% icc -isysroot icc -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX13.1.sdk -o binary source.c

Could you provide some context? Where are you seeing this? In what application? On what device?

ls -ld /usr  /usr/include
drwxr-xr-x. 17 root root   255 Sep 21  2021 /usr/
drwxr-xr-x. 98 root root 12288 Dec 11 03:50 /usr/include/

The 'd' in column 1 says it is a directory, NOT a Symbolic Link
