This directory contains files copied from: /Library/Developer/CommandLineTools/SDKs/MacOSX12.3.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers We cannot put this directory on VeriFast's include path because it contains the file stdbool.h which VeriFast cannot parse.

More specifically, VeriFast cannot parse the defines #define false 0 and #define true 1 contained in the header stdbool.h. Therefore, by default, it skips all includes of stdbool.h and uses its builtin definitions of true and false. However, if we manually specify an include path (via VeriFast's -I option) that contains stdbool.h, this behaviour changes. It stops skipping these includes which leads to parse errors.
