The GNUPro toolchain that comes with the board is not capable of supporting
eCos I'm afraid. A number of modifications and fixes were made to the tools
since the tools given to NEC were developed. Sorry if that isn't what you
wanted to hear :-/. In particular, the port of eCos to the vrc4373 uses
32-bit integer registers, not the full 64-bit. 

You can still build your own tools as described on the eCos web site; or
something can be arranged if you wished to purchase the eCos Developer's
Kit - although I think you investigated that option already?
