[PATCH][libstdc++-v3 parallel mode] Tackle further XXX todos

[Johannes Singler]

Okay, let's continue:

types.h  // XXX need to use <cstdint>
         // XXX numeric_limits::digits?

How do you like the attached patch?


Tested x86_64-unknown-linux-gnu: No regressions

Please approve for mainline.

        * include/parallel/base.h: Take integer types from
        <tr1/cstdint>.
        * include/parallel/compatibility.h: Likewise.
        * include/parallel/multiseq_selection.h: Likewise.
        * include/parallel/random_shuffle.h: Likewise.
        * include/parallel/random_number.h: Likewise;
        use numeric_limits<>::digit instead of sizeof()*8.
        * include/parallel/types.h: Likewise.



// XXX atomics interface?

Very good idea, but how do I bring it in?  Already

#include <cstdatomic>

or

#include <stdatomic.h>

make the compilation fail.  Is there any way to get access to the
functions without enabling the C++0x mode?  Hmm, declaring functions
volatile does not seem backwards-compatible.
