thread entrypoints: (lwpSelect, shutdown_sequence): Parameters didn't match thread entry point prototype. (lwpEntryPoint): Arguments didn't match thread entry point prototype. Change linkage of functions without prototype declaration to static where possible. Remove some superflous declarations, replace others by suitable includes.
