 However, if you compile CNI code with the standard ABI, you can call

+@item -fbootstrap-classes
+This option can be use to tell @code{libgcj} that the compiled classes
+should be loaded by the bootstrap loader, not the system class loader.
+By default, if you compile a class and link it into an executable, it
+will be treated as if it was loaded using the system class loader.
+This is convenient, as it means that things like
+@code{Class.forName()} will search @samp{CLASSPATH} to find the
+desired class.
