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