// Function body near the middle of the file
static void SetFunctionPointers();
// We used to jump through some hoops to set the function pointers once,
// including std::call_once. Later we learned std::call_once was fairly
// buggy due to interactions between libstdc++, glibc and pthreads.
// Now we use a double-checked pattern. We are not leaking anything so
// it does not matter if a pointer is written twice during a race.
// Also see GCC Issue 66146, "call_once not C++11-compliant" (on many
// platforms), http://gcc.gnu.org/bugzilla/show_bug.cgi?id=66146 and
// Use a double-checked pattern. We are not leaking anything so it
// does not matter if a pointer is written twice during a race.
// Avoid std::call_once due to too many problems on platforms like
// Solaris and Sparc. Also see
