	Maybe.  I didn't remember.  I assume Dr. Boehm will keep the GCC
and external versions in sync anyway.

	I did not mean the programmer explicitly calling GC_INIT, I meant
either an implicit macro when the main Java program is invoked or
something like a static constructor (placing GC_INIT in a function).

	If you do not call GC_INIT, you are not invoking boehm-gc
correctly, as that is part of the API.  libgcj also may not work properly
on Windows or AIX which utilize that GC_INIT.
