    sync/atomic: use strong form of atomic_compare_exchange_n
    
    In the recent change to use atomic_compare_exchange_n I thought we
    could use the weak form, which can spuriously fail. But that is not
    how it is implemented in the gc library, and it is not what the rest
    of the library expects.
    
    Thanks to Lynn Boger for identifying the problem.

    • Fix locations in conversion_null_warnings (PR c++/71302) · aa9dc193 
      PR c++/71302 reports that g++ shows poor locations for
-Wzero-as-null-pointer-constant for pointers in function calls,
using the close parenthesis of the call, rather than showing the
pertinent argument.

This particular case was fixed in GCC 8, but regressed on trunk
in r260973.

This patch fixes the regression, and adds column numbers to the
test cases (where they're correct) to avoid regressing them in the
future.  There are still various places where the locations aren't
correct, but fixing them isn't stage 4 material.

gcc/cp/ChangeLog:
	PR c++/71302
	* call.c (get_location_for_expr_unwinding_for_system_header): New
	function.
	(conversion_null_warnings): Use it when getting locations for
	EXPR, effectively adding a call to
	get_location_for_expr_unwinding_for_system_header for
	-Wconversion-null and making use of EXPR_LOCATION for
	-Wzero-as-null-pointer-constant.

    • Fix type of extern array declared in inner scope with outer initialization shadowed (PR c/88584). · fbe83e6b 
      As reported in bug 88584, if you have a file-scope array with external
linkage, initialized at file scope, and that array is shadowed at
block scope, and is declared again with external linkage and an
incomplete type in an inner scope, it is wrongly given a complete type
in that inner scope when the correct C semantics give it an incomplete
type (only the visible declarations contribute to the type in a given
scope).

In general, issues with the types of external linkage declarations
being different in different scopes were addressed by my fixes for bug
13801, for GCC 4.0.  In this case, however, the code in pushdecl
dealing with giving declarations the right type in each scope works
fine, and the type is subsequently modified by complete_array_type
called from finish_decl: finish_decl is trying to complete an array
type based on an initializer, but that's only correct for the original
initialization at file scope, not for such a declaration in an inner
scope (it's harmless but unnecessary in the case where the original
declaration is still visible in the inner scope).  Thus, this patch
changes finish_decl to stop this logic applying for such an external
declaration in an inner scope.  (An erroneous attempt to include an
initializer for an extern variable in an inner scope is diagnosed
elsewhere.)

This is a regression from GCC 3.4, which properly rejected the code in
question (quite likely by accident).

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

gcc/c:
	PR c/88584
	* c-decl.c (finish_decl): Do not complete array types for arrays
	with external linkage not at file scope.

gcc/testsuite:
	PR c/88584
	* gcc.dg/redecl-18.c: New test.
