Fix potential ABI change introduced by glibc-rh1398413.patch.
 
extern void _IO_str_init_static (struct _IO_strfile_ *, char *, int, char *)
     __THROW;
extern void _IO_str_init_readonly (struct _IO_strfile_ *, const char *, int)
     __THROW;
 
Upstream, this did not have any effect because the function definitions
were prototypes, so there is no upstream fix necessary.
 
But downstream, we have:
 
     70 void
     71 _IO_str_init_static (sf, ptr, size, pstart)
     72      _IO_strfile *sf;
     73      char *ptr;
     74      int size;
     75      char *pstart;
     76 {
     77   return _IO_str_init_static_internal (sf, ptr, size < 0 ? -1 : size, pstart);
     78 }
     79 
     80 void
     81 _IO_str_init_readonly (sf, ptr, size)
     82      _IO_strfile *sf;
     83      const char *ptr;
     84      int size;
     85 {
     86   _IO_str_init_static_internal (sf, (char *) ptr, size < 0 ? -1 : size, NULL);
     87   sf->_sbf._f._IO_file_flags |= _IO_NO_WRITES;
     88 }
 
This results in:
 
strops.c:71:1: warning: function declaration isn't a prototype [-Wstrict-prototypes]
strops.c:81:1: warning: function declaration isn't a prototype [-Wstrict-prototypes]
 
It is a potential ABI change, depending on the architecture.  None of
the architectures in Red Hat Enterprise Linux appear to be affected,
though.
