54 * For the shared version of the threads library, the above is sufficient.
55 * But for the archive version of the library, we need a little bit more.
56 * Namely, we must arrange for this particular module to be pulled in from
57 * the archive library at link time. To accomplish that, we define and
58 * initialize a variable, "_thread_autoinit_dummy_decl". This variable is
59 * referenced (as an extern) from libc/stdlib/exit.c. This will always
60 * create a need for this module, ensuring that it is present in the
63 extern int _thread_autoinit_dummy_decl;
