By default, ILINK determines automatically which variant of the standard library to include during linking. The decision is based on the sum of the runtime attributes available in each object file and the library options passed to ILINK.

To disable the automatic inclusion of the library, use the option ‑‑no_library_search. In this case, you must explicitly specify every library file to be included. For information about available library files, see Prebuilt runtime libraries.
