| /long_path/stl_construct.h: In function 'void
| __static_initialization_and_destruction_0(int, int)':
| /long_path/stl_construct.h:81: warning: 'SR.133' is used uninitialized in this
| function
| 
| Apart from the strange variable name 'SR.133' the warning seems to be
| justified as the default constructor of _List_iterator does not initialize
| the pointer _M_node. _List_const_iterator has the same problem.

That strange warning would be greatly useful if SRA names were not
used.  They make the diagnostic rather cryptic and noisy.

I think your patch is OK and should be applied.
