    Log Message:
    We must explicitly set _FILE_OFFSET_BITS=64 to use Linux OFD locks

    The Linux lock() implementation in xpdev/filewrap.c requires that _FILE_OFFSET_BITS is set to 64 or else OFD (sane) locks are not
    used on Linux, defaulting back to the crazy per-process file region
    locking of Linux of old. This was done in this commit: http://cvs.synchro.net/commitlog.ssjs?99999#39639
    because:
    https://patchwork.kernel.org/patch/9289177/

    but on 64-bit Linux, large file support is assumed and you don't
    actually need to define _FILE_OFFFSET_BITS, we're peforming this
    check for 32-bit Linuxes. Perhaps a check to see if sizeof(off_t)
    == 8 would have been better. However, this change enables OFD
    Locks for *all* flavors of Linux (not just 64-bit) - so that's
    better.

    Why do we care? Because using region locks on the same file in
    a multi-threaded program doesn't really work right on Linux without
    using OFD Locks. I saw this problem with receiving multiple
    simultaneous emails in the mailserver and getting smb_locksmbhdr() errors/failures when trying to save the message data or headers
    of the one or more messages every time GitLab would send email
    out to those whoe have opted-in to received email notifications
    upon gitlab.synchro.net activity.

    Add -std=c++11 for .cpp builds

    Hope to address error reported by rjwboys via IRC when using
    gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.12)
    from ansiterm.cpp:22 /user/include/c++/5/bits/c++0x_warning.h:32:2
    error #error this file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
