* include/endian.h: Move everything into this file and define things more like linux. * include/cygwin/types.h: Include endian.h. * include/sys/dirent.h: Define DT_* types and conversion macros. * pinfo.cc (pinfo::init): Remove special handling for PID_ALLPIDS and execed code, even though it probably still isn't quite right.

Also, if __BSD_VISIBLE * LITTLE_ENDIAN, * BIG_ENDIAN, * PDP_ENDIAN, and * BYTE_ORDER. Targets that define __machine_host_to_from_network_defined in <machine/_endian.h> must provide their own implementation of * __htonl(), * __htons(), * __ntohl(), and * __ntohs(), otherwise a default implementation is provided by <machine/endian.h>. In case of GCC defines to builtins are used. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
