        * Makefile: Rebuilt.
	* Makefile.am (toolexeclibdir): Add $(MULTISUBDIR) even for native
	builds.

	* java/net/natPlainSocketImpl.cc: Include <sys/select.h> only if
	present.

	* configure: Rebuilt.
	* configure.in: Properly align --help output, fix capitalization
	and punctuation.
	* acinclude.m4: Likewise.

1999-08-09  Kresten Krab Thorup  <krab@gnu.org>

	* include/javaprims.h (_Jv_word, _Jv_word2): New types.

	* include/java-interp.h (_Jv_InterpMethodInvocation): Use _Jv_word.
	(_Jv_callInterpretedMethod): Unused. Remove.
	(_Jv_InterpMethod::run,run_normal,run_synch_object,run_synch_class):
	Use ffi_raw.
	* include/java-cpool.h (_Jv_get, _Jv_put): Remove.
	(_Jv_{store,load}{Indexes,Int,Float,Long,Double}): Use _Jv_word.
	* boehm.cc (_Jv_MarkObj): Use _Jv_word.
	* interpret.cc: use _Jv_word.
	* defineclass.cc: use_Jv_word.
	* resolve.cc: Use _Jv_word.
	(_Jv_ResolvePoolEntry): Return _Jv_word.
	* java/lang/Class.h (_Jv_Constants): Use _Jv_word for cpool.
	* java/lang/natClassLoader.cc (_Jv_InternClassStrings): Use _Jv_word.

	* interpret.cc (gnu::gcj::runtime::MethodInvocation::continue1):
	Change comment.

- * if double or long has alignment greater than void *.  On an 64-bit
