= `BOOST_ARCH_WORD_BITS`

Detects the native word size, in bits, for the current architecture. There are
two types of macros for this detection:

* `BOOST_ARCH_WORD_BITS`, gives the number of word size bits
  (16, 32, 64).
* `BOOST_ARCH_WORD_BITS_16`, `BOOST_ARCH_WORD_BITS_32`, and
  `BOOST_ARCH_WORD_BITS_64`, indicate when the given word size is
  detected.

They allow for both single checks and direct use of the size in code.

NOTE: The word size is determined manually on each architecture. Hence use of
the `wordsize.h` header will also include all the architecture headers.
