557
558 On Windows, the system behaves a little differently when two
559 objfiles each define a global symbol using the same name, compared
560 to other platforms such as GNU/Linux for instance. On GNU/Linux,
561 all instances of the symbol effectively get merged into a single
562 one, but on Windows, they remain distinct.
563
564 As a result, it usually makes sense to start global symbol searches
565 with the current objfile before expanding it to all other objfiles.
566 This helps for instance when a user debugs some code in a DLL that
567 refers to a global variable defined inside that DLL. When trying
568 to print the value of that global variable, it would be unhelpful
569 to print the value of another global variable defined with the same
