No, since gij will just ignore unrecognized -X options.  I put in a
skeleton for handling these options as a hint to people implementing
similar options in the future.  Where possible, I think we should reuse
the -X option names.  For example, if we add strict JNI checking support
to libgcj, we'll want to wire that into -Xcheck:jni.  The current
skeleton documents all the -X options recognized by Sun's 1.5 java
command.

I thought that since we export JvMalloc we should also export JvRealloc.
I've added a "Memory allocation" section to the CNI manual that
documents these functions.

This new patch incorporates all your suggestions and updates the
manual's CNI and "Invoking gij" sections.
