I have been very patient up to now. Why can't you try your own idea?

I tried m4_rename and m4_pushdef in libjava like

aclocal won't include ltgcc.m4. When I include it in configure.ac,
it still doesn't work. The order of ltgcc.m4 and libtool.m4 may be
important.
Sorry, I have too many other gcc things to deal with at the moment. I
don't think I can spend more time on this.
