2005-11-21  Joel Sherrill <joel.sherrill@oarcorp.com>

	* socket.c: Add extern int h_errno for rtems since networking header
	files are not available at this point in a tool bootstrap. Newlib

	* config/arm/rtems-elf.h: Added definition of LINK_GCC_C_SEQUENCE_SPEC
	which matches behavior of gcc 4.0 and older for RTEMS targets.  The
	default now includes a linker group which makes the RTEMS one nest.
