When we integrated GCJ/libgcj, it looks like we did not proceed
doing that fully as it came to the web pages, and sadly nobody
else has been looking after them for a while.
2014-06-30 Gerald Pfeifer <ger...@pfeifer.com>
* build-snapshot.html: Remove.
* gcj2.html: Remove link to build-snapshot.html and GCC homepage.
* libgcj2.html: Replace link to build-snapshot.html by our main
installation instructions. Omit redundant instructions.
Applied.

<h2>How to build it</h2>
- <p>Just follow the directions for
- <a href="build-snapshot.html">building</a> GCJ.</p>
-
- <p>There are a few options you might consider passing to
- ``configure'':</p>
-
- <dl>
- <dt>--enable-java-gc=TYPE</dt>
- <dd>Enables the garbage collector. The default type is
- ``boehm'', for the Boehm conservative GC.</dd>
-
- <dt>--enable-fast-character</dt>
- <dd>libgcj includes two implementations of java.lang.Character.
- The default implementation is small, but slow. This option will
- enable the faster, larger code.</dd>
-
- <dt>--enable-threads=TYPE</dt>
- <dd>libgcj includes a retargetable thread layer. The value of
- this option must be the same as the value used when building
- gcj itself.
- By default, no threads will be used (this is a crummy default,
- but we just follow GCC here).
- The only supported values are ``none'' (for no threads) and
- ``posix'' (for POSIX threads).</dd>
-
- </dl>
+ <p>Just follow our <a href="https://gcc.gnu.org/install/";>installation
+ instructions</a>.</p>

- $ tar xfv *.tar

-
- Have a look at the toplevel configure.in (gcc/configure.in) and
- make sure that the variable `noconfigdirs' isn't assigned to
- something (like target-libjava or ${libgcj}.)

- Also, check for platform-specific assignments of `noconfigdirs' with
- ${libgcj}; if ${libgcj} is listed for your platform, remove it before
