in arguments of MiG routines must be declared as `const'

[Ognyan Kulev]

Hi,

Take a look at libstore/file.c:file_write.  We have

static error_t
file_write (struct store *store,
            store_offset_t addr, size_t index, const void *buf,
            size_t len, size_t *amount)
{
  size_t bsize = store->block_size;
  return io_write (store->port, buf, len, addr * bsize, amount);
}

but the second argument of MiG prototyped io_write is not const and gcc 
prints warning.

There are 24 warning of this type but forget them: more importantly the 
correct way to prototype [in] arguments in MiG is they to be const when 
they are arrays.  This would require changing the MiG generator, and 
many definitions in Hurd servers and libraries.  Quite a mass change.

I would like to do this.  Is it correct that the MiG generator and *_S_* 
definitions are the only places to be touched?

Regards
