-/* Weaks for application/library use.

* We need to define weaks here to cover all the pthread functions that
- * libc itself will use so that we aren't forced to link libc.so to
- * libpthread.so. When an application doesn't use pthreads support,
- * the locking functions used by libc itself basically become no-ops.
- * However, if the application uses pthreads, then it will pull in
- * libpthread.so whose symbols will override these weaks magically
- * turning the internal libc mutex calls from no-ops to real locking
- * calls.
+ * libc itself will use so that we aren't forced to link libc against
+ * libpthread. This file is only used in libc.a and since we have
+ * weaks here, they will be automatically overridden by libpthread.a
+ * if it gets linked in.
