|---|
| 32 | |
|---|
| 33 | <p>Boost.Build's <a href="http://gcc.gnu.org">gcc</a> toolset supports the |
|---|
| 34 | GNU GCC compiler on a variety of Unices, including (but not limited to) |
|---|
| 35 | SunOS, BeOS, MacOS X, and of course Linux. For Windows users, it also |
|---|
| 36 | supports <a href="http://www.cygwin.com">Cygwin</a> GCC, though <a href= |
|---|
| 37 | "http://www.mingw.org">MinGW</a> has <a href="mingw-tools.html">its own |
|---|
| 38 | distinct toolset</a>.</p> |

| 40 | <h2><a name="configuration" id="configuration">Configuration |
|---|
| 41 | Variables</a></h2>The gcc toolset responds to the following variables, |

| 42 | which can be set in the environment or configured on the jam command-line |
