-
-@table @gcctabopt
-@item --no-assert
-Don't recognize the @code{assert} keyword, for backwards compatibility
-with older versions of the language specification.
-
-@item --complexity
-This prints a complexity measure, related to cyclomatic complexity, for
-each input file.
-
-@item --encoding=@var{name}
-This works like the corresponding @command{gcj} option.
-
-@item --print-main
-This prints the name of the class in this file containing a @code{main}
-method.
-
-@item --list-class
-This lists the names of all classes defined in the input files.
-
-@item --list-filename
-If @code{--list-class} is given, this option causes @code{jv-scan} to
-also print the name of the file in which each class was found.
-
-@item -o @var{file}
-Print output to the named file.
-
-@item --help
-Print help, then exit.
-
-@item --version
-Print version number, then exit.

@noindent The following function definition is the template for all such functions:

-Create's an array @var{length} indices long.
+Creates an array @var{length} indices long.
@end deftypefun
@deftypefun jsize JvGetArrayLength (jarray @var{array})
The names and interfaces are analogous to those of @acronym{JNI}.
-@deftypefun jstring JvNewString (const char* @var{chars}, jsize @var{len})
-Returns a Java @code{String} object with characters from the C string
-@var{chars} up to the index @var{len} in that array.
+@deftypefun jstring JvNewString (const jchar* @var{chars}, jsize @var{len})
+Returns a Java @code{String} object with characters from the array of
+Unicode characters @var{chars} up to the index @var{len} in that array.
@end deftypefun
@deftypefun jstring JvNewStringLatin1 (const char* @var{bytes}, jsize @var{len})
is wrapped with a try/catch block to provide a default handler for any uncaught
exceptions.

+@item gnu.gcj.user.realname
+The real name of the user, as taken from the password file. This may
+not always hold only the user's name (as some sites put extra
+information in this field). Also, this property is not available on
+all platforms.
+
@item gnu.gcj.runtime.NameFinder.use_addr2line
Whether an external process, @command{addr2line}, should be used to determine
line number information when tracing the stack. Setting this to @code{false}
significantly for applications that print stack traces or make logging calls
frequently.
+@item gnu.gcj.runtime.NameFinder.show_raw
+Whether the address of a stack frame should be printed when the line
+number is unavailable. Setting this to @code{true} will cause the name
+of the object and the offset within that object to be printed when no
+line number is available. This allows for off-line decoding of
+stack traces if necessary debug information is available. The default
+is @code{false}, no raw addresses are printed.
+
+@item gnu.gcj.runtime.NameFinder.remove_unknown
+Whether stack frames for non-java code should be included in a stack
+trace. The default value is @code{true}, stack frames for non-java
+code are suppressed. Setting this to @code{false} will cause any
+non-java stack frames to be printed in addition to frames for the java
+code.

built-in class loader. If this property is set to @samp{full}, a full
