----
BOOST_VERSION_NUMBER(major,minor,patch)
----
Defines standard version numbers, with these properties:
* Decimal base whole numbers in the range [0,1000000000).
The number range is designed to allow for a (2,2,5) triplet.
Which fits within a 32 bit value.
* The `major` number can be in the [0,99] range.
* The `minor` number can be in the [0,99] range.
* The `patch` number can be in the [0,99999] range.
* Values can be specified in any base. As the defined value
is an constant expression.
* Value can be directly used in both preprocessor and compiler
expressions for comparison to other similarly defined values.
* The implementation enforces the individual ranges for the
major, minor, and patch numbers. And values over the ranges
are truncated (modulo).

version number resulting in a preprocessor expression in the range of
[0,99] or [0,99999] for the major and minor, or patch numbers
respectively.
