+vda: here's why:
 In libpthread/linuxthreads.old/sysdeps/pthread/bits/libc-lock.h
 adding libc_hidden_proto(foo) just before weak_extern (__pthread_initialize)
 will not warn:
-    //libc_hidden_proto(foo)

     weak_extern (__pthread_initialize)
-    //libc_hidden_proto(foo)
+    /* libc_hidden_proto(foo) */
 but adding after will! Which is extremely strange -
 weak_extern expands into just "#pragma weak __pthread_initialize".
 TODO: determine whether it is a gcc bug or what
-(see gcc.gnu.org/bugzilla/show_bug.cgi?id=36282).
+(see gcc.gnu.org/PR36282).
 For now, just include all headers before internals.h
 (they are again included in internals.h - maybe remove them there later)
