System: UNIX_SV rapture 4.2MP 2.01 i386 x86at


	<machine, os, target, libraries (multiple lines)>
host: i386-pc-sysv4.2uw2.01
build: i386-pc-sysv4.2uw2.01
target: i386-pc-sysv4.2uw2.01
configured with: ./configure --with-gnu-as --with-gnu-ld
>Description:
	__i386__ not defined via specs file.

	__i386__ present in *cpp_cpu: section, but apparently this doesn't get
sent to the preprocessor command line.

	this causes problems with <sys/byteorder.h> which thinks the intel box is BIG_ENDIAN
	because __i386__ is not defined
