/* Macros for compiler / platform specific features and build options.\r
\r
   Build options are:\r
    * BROTLI_BUILD_32_BIT disables 64-bit optimizations\r
    * BROTLI_BUILD_64_BIT forces to use 64-bit optimizations\r
    * BROTLI_BUILD_BIG_ENDIAN forces to use big-endian optimizations\r
    * BROTLI_BUILD_ENDIAN_NEUTRAL disables endian-aware optimizations\r
    * BROTLI_BUILD_LITTLE_ENDIAN forces to use little-endian optimizations\r
    * BROTLI_BUILD_MODERN_COMPILER forces to use modern compilers built-ins,\r
      features and attributes\r
    * BROTLI_BUILD_PORTABLE disables dangerous optimizations, like unaligned\r
      read and overlapping memcpy; this reduces decompression speed by 5%\r
    * BROTLI_DEBUG dumps file name and line number when decoder detects stream\r
      or memory error\r
    * BROTLI_ENABLE_LOG enables asserts and dumps various state information\r
