Introduction</h2> 783<div class="sectionbody"> 784<div class="paragraph"> 785<p>This library defines a set of compiler, architecture, operating system, 786library, and other version numbers from the information it can gather of 787C, C++, Objective C, and Objective C++ predefined macros or those defined 788in generally available headers. The idea for this library grew out of a 789proposal to extend the Boost Config library to provide more, and consistent, 790information than the feature definitions it supports. What follows is 791an edited version of that brief proposal.</p> 792</div> 793<div class="sect2"> 794<h3 id="_proposal"><a class="anchor" href="#_proposal"></a>1.1. Proposal</h3> 795<div class="paragraph"> 796<p>The idea is to define a set of macros to identify compilers and 797consistently represent their version. This includes:</p> 798</div> 799<div class="ulist"> 800<ul> 801<li> 802<p>A unique BOOST_VERSION_NUMBER(major,minor,patch) macro to specify version 803numbers (unfortunately, the name BOOST_VERSION is already taken to designate 804the version number of boost itself).</p> 805</li> 806<li> 807<p>A compiler identification macro, suitable for use in <code>#if</code>/<code>#elif</code> directives, 808for each of the supported compilers. All macros would be defined, regardless 809of the compiler. The one macro corresponding to the compiler being used would 810be defined, in terms of BOOST_VERSION_NUMBER, to carry the exact compiler 811version. All other macros would expand to an expression evaluating to false 812(for instance, the token 0) to indicate that the corresponding compiler is not 813present.</p> 814</li> 815<li> 816<p>"Null values" could be set, for all macros, in 817boost/config/select_compiler.hpp; then, for each compiler the corresponding 818identification macro would be #undef and re-#defined in the corresponding 819boost/compiler/(cc).hpp; however in the context of the Boost.Config 820infrastructure using a "prefix" header (to be introduced) or 821boost/config/suffix.hpp is a better solution.</p> 822</li> 823</ul> 824</div> 825</div> 826<div class="sect2"> 827<h3 id="_current_library"><a class="anchor" href="#_current_library"></a>1.2.
