/*  This file figures out which platform is being built, and defines some macros
    that the rest of the code can use for OS-specific compilation.

    Macros that will be set here are:

    - One of BEAST_WINDOWS, BEAST_MAC BEAST_LINUX, BEAST_IOS, BEAST_ANDROID, etc.
    - Either BEAST_32BIT or BEAST_64BIT, depending on the architecture.
    - Either BEAST_LITTLE_ENDIAN or BEAST_BIG_ENDIAN.
    - Either BEAST_INTEL or BEAST_PPC
    - Either BEAST_GCC or BEAST_MSVC
