So, it seem that using (1) and (2) resolves this issue:

Index: std_bitset.cpp
===================================================================
--- std_bitset.cpp	(revision 60227)
+++ std_bitset.cpp	(working copy)

 int test_main(int, char*[])
 {
   typedef std::bitset<8> bitset_type;
-  const bitset_type initial_value1 = 1ul;
-  const bitset_type initial_value2 = 2ul;
+  const bitset_type initial_value1(1);
+  const bitset_type initial_value2(2);
 
   bitset_type object1 = initial_value1;
   bitset_type object2 = initial_value2;

Tested with msvc-10.0, msvc-9.0 and gcc-4.4 (mingw)

Yours,

Jürgen
