If you wish to modify @file{.java} files in libjava, you will need to

to have executables named @command{ecj1} and @command{gjavah} in your path.

@item --enable-java-maintainer-mode
By default the @samp{libjava} build will not attempt to compile the
@file{.java} source files to @file{.class}. Instead, it will use the
@file{.class} files from the source tree. If you use this option you
must have executables named @command{ecj1} and @command{gjavah} in your path
for use by the build. You must use this option if you intend to
modify any @file{.java} files in @file{libjava}.
@item --with-java-home=@var{dirname}
This @samp{libjava} option overrides the default value of the
@samp{java.home} system property. It is also used to set
@samp{sun.boot.class.path} to @file{@var{dirname}/lib/rt.jar}. By
default @samp{java.home} is set to @file{@var{prefix}} and

@item --with-ecj-jar=@var{filename}
This option can be used to specify the location of an external jar
file containing the Eclipse Java compiler. A specially modified
version of this compiler is used by @command{gcj} to parse
@file{.java} source files. If this option is given, the
@samp{libjava} build will create and install an @file{ecj1} executable
which uses this jar file at runtime.
If this option is not given, but an @file{ecj.jar} file is found in
the topmost source tree at configure time, then the @samp{libgcj}
build will create and install @file{ecj1}, and will also install the
discovered @file{ecj.jar} into a suitable place in the install tree.
If @file{ecj1} is not installed, then the user will have to supply one
on his path in order for @command{gcj} to properly parse @file{.java}
source files. A suitable jar is available from
