// On AIX, and perhaps other systems, library initialization order is

// not guaranteed.  For example, the static initializers for the main

// program might run before the static initializers for this library.

// That means that we cannot rely on static initialization in the

// library; there is no guarantee that things will get initialized in

// time.  This file contains definitions of all global variables that

// require initialization as arrays of characters.

// NB: asm directives can rename these non-exported, namespace

// __gnu_cxx symbols into exported, namespace std symbols with the

// appropriate symbol version name.

// The rename syntax is 

//   asm (".symver currentname,oldname@@GLIBCXX_3.2")

// In macro form:

// _GLIBCXX_ASM_SYMVER(currentname, oldname, GLIBCXX_3.2)

_GLIBCXX_BEGIN_NAMESPACE(std)

  // Standard stream objects.

  // NB: Iff <iostream> is included, these definitions become wonky.
