C99 adds a new - keyword, <code class="code">restrict</code>, to apply to individual pointers. The - C++ solution is contained in the library rather than the language - (although many vendors can be expected to add this to their compilers - as an extension). - </p><p>That library solution is a set of two classes, five template classes, - and "a whole bunch" of functions. The classes are required - to be free of pointer aliasing, so compilers can optimize the - daylights out of them the same way that they have been for FORTRAN. - They are collectively called <code class="code">valarray</code>, although strictly - speaking this is only one of the five template classes, and they are - designed to be familiar to people who have worked with the BLAS - libraries before. - </p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a id="numerics.c.c99"></a>C99</h3></div></div></div><p>In addition to the other topics on this page, we'll note here some - of the C99 features that appear in libstdc++. - </p><p>The C99 features depend on the <code class="code">--enable-c99</code> configure flag. - This flag is already on by default, but it can be disabled by the - user. Also, the configuration machinery will disable it if the - necessary support for C99 (e.g., header files) cannot be found. - </p><p>As of GCC 3.0, C99 support includes classification functions - such as <code class="code">isnormal</code>, <code class="code">isgreater</code>, - <code class="code">isnan</code>, etc. - The functions used for 'long long' support such as <code class="code">strtoll</code> - are supported, as is the <code class="code">lldiv_t</code> typedef.
