	* ld-symbolic.m4: New.

libjava/

2007-01-14  H.J. Lu  <hongjiu.lu@intel.com>

	* Makefile.am (libgcj_la_LDFLAGS): Add
	$(LIBGCJ_LD_SYMBOLIC_FUNCTIONS).
	(libgcj_tools_la_LDFLAGS): Likewise.
	(libgcj_bc_la_LDFLAGS): Likewise.
	* Makefile.in: Regenerated.

	* configure.ac: Use ACX_PROG_LD_GNU_SYMBOLIC.  Set
	LIBGCJ_LD_SYMBOLIC_FUNCTIONS to $SYMBOLIC_LDFLAGS.  Set
	libgcj_ld_symbolic to $SYMBOLIC_LDFLAGS if it isn't set.
	Substitute LIBGCJ_LD_SYMBOLIC_FUNCTIONS.
	* configure: Regenerated.
	* aclocal.m4: Likewise.
	* gcj/Makefile.in: Likewise.
	* include/Makefile.in: Likewise.
	* testsuite/Makefile.in: Likewise.
