The `struct rusage' type should be declared by <sys/resource.h>
(actually in <resourcebits.h> on my system, but that file is included
in <sys/resource.h>.  Does your system have <sys/resource.h>?  Did
configure find it?

BTW, why are you using `-m486' and `-fno-strength-reduce' in CFLAGS?
Are you also using them in CXXFLAGS (the output above seems a bit
mangled).  Using -fno-strength-reduce for Octave's C++ code can lower
its performance considerably.

Please report bugs in Octave to the bug-octave mailing list.  If you
are unsure of what to include in a bug report so that it will be
useful in helping someone to fix the bug, please read the `How to
Report Bugs' section in the Octave manual.

Thanks,
