<h2>Introduction</h2>
<p>Boost.Build's <a href="http://gcc.gnu.org">gcc</a> toolset supports the
GNU GCC compiler on a variety of Unices, including (but not limited
to) SunOS, BeOS, MacOS X, and of course Linux. For Windows users, it
also supports <a href="http://www.cygwin.com">Cygwin</a> GCC, though
<a href="http://www.mingw.org">MinGW</a> has <a
href="mingw-tools.html">its own distinct toolset</a>.
<h2><a name="configuration">Configuration Variables</a></h2>
The gcc toolset responds to the following variables, which can be set in the
environment or configured on the jam command-line using
<code>-s<i>VARIABLE_NAME</i>=</code><i>value</i>:
<table border="1">
<tr><th>Variable Name <th>Semantics <th>Default <th>Notes
<tr>
<td><code>GCC_ROOT_DIRECTORY</code>
<td>The directory in which GCC was installed.
<td><code>&quot;&quot;</code> (the empty string)
<td>Usually, there is no need to set this variable at
all. However, if g++ is not in the path it is usually
sufficient to configure this one variable. More fine-grained
configuration is available by setting the variables below.
<tr>
<td><code>GCC_BIN_DIRECTORY</code>
<td>The directory prefix used to find the gcc executables
<td><code>$(GCC_ROOT_DIRECTORY)/bin/</code>, or "" if <code>GCC_ROOT_DIRECTORY</code> is
not set.
<tr>
<td><code>GCC_INCLUDE_DIRECTORY</code>
<td> The directory in which to find system includes.
<td>
<i>empty</i>.
<td>Normally, GCC installations can locate their own system includes
without assistance.
<tr>
<td><code>GCC_STDLIB_DIRECTORY</code>
<td> the directory in which to find the standard library
objects associated with this build of gcc.
<td>
<code>$(GCC_ROOT_DIRECTORY)/lib</code>.
<tr>
<td><code>GXX</code>
<td>The name by which g++ is invoked.
<td><code>g++</code>
<td>
May be used in lieu of setting the <code>&lt;cxxflags&gt;</code>
property to force options such as
&quot;<code>-V3.0.4</code>&quot; into the g++ command line:
&quot;<code>-sGXX=g++ -V3.0.4</code>&quot;.
<tr>
<td><code>GCC</code>
<td>Similar to GXX, the name by which gcc is invoked for "C"
language targets.
<td><code>gcc</code>
