// 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)
