[Michael Snyder <msnyder@vmware.com>]

Since these aren't available on all hosts, let's use the
"native gdb" method.

2009-10-23  Michael Snyder  <msnyder@vmware.com>

	* record.c (top level): Don't include byteswap.h.
	(netorder64): Use store_unsigned_integer instead of bswap_64.
	(netorder32): Use store_unsigned_integer instead of bswap_32.
	(netorder16): Use store_unsigned_integer instead of bswap_16.
