CDT indexer and operator __has_builtin

[gvl2023]

Does the indexer recognize the __has_builtin operator? Getting red squiggly lines for std::source_location, GCC header source_location has this guard which the indexer thinks evaluates to false:

#if __cplusplus > 201703L && __has_builtin(__builtin_source_location)

__cplusplus is 202002L, so it's the second term. I tried to add __builtin_source_location as a built-in macro under Preprocessor Include Paths, Macros etc./CDT User Settings Entries to no avail.
