Sorry, I never compiled the big endian configuration. It just takes to long
on my 486/33 (Donations accepted :-) For a quick fix it should be sufficient
to move the define in linux.h down to the end of the file.
About including svr4 - I have to override lots of definitions from svr4
because MIPS svr4 systems are a bit different often. When I've got nothing
else left do I'll one day clean up that file in a way that it won't use the
svr4 stuff any more.
Hope that helps & thanks for the bug report,
