RE: GCC 2.8.1 and binutils for i960-wrs-vxworks

[rfreier at csw dot L-3com dot com]

Finally figured out the problem,
so I'm answering my own question.
Here's the (rather simple) answer:

You must build both the binutils and GCC for the
target i960-wrs-vxworks5.3, not i960-wrs-vxworks.
If you try the latter, the binutils and GCC will
not agree on the configuration.  GCC will be expecting
to use coff, and the binutils will producing a.out.

REALLY stupid mistake.
