 /* 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.
+ */
+
+/* glibc itself defines all these, but we don't need them in uClibc
+ *
  * Verified by comparing to glibc's linuxthreads/forward.c and defined
  * only those that are in the glibc abi.
  * The commented aliases are ones that were previously defined in uClibc
  * and which I left in for documentation.
