[RFC] pthread_create generic argument passing

[Diego Nieto Cid]

Hello,

So in the hurd package build log there appears this couple of log
messages:

    ../../nfsd/loop.c: In function 'server_loop':
    ../../nfsd/loop.c:41:12: warning: cast from pointer to integer of different 
size [-Wpointer-to-int-cast]
       41 |   int fd = (int) arg;
          |            ^

    ../../nfsd/main.c: In function 'create_server_thread':
    ../../nfsd/main.c:47:54: warning: cast to pointer from integer of different 
size [-Wint-to-pointer-cast]
       47 |   fail = pthread_create (&thread, NULL, server_loop, (void *) 
socket);
          |   

Is there really no way to get this warning fixed? It looks like the standard
way of passing generic arguments to a thread function. So we'll probable need
to live with it.

Thanks,
Diego
