I get the following output when compiling with the C++ 9 (21) compiler in VS2003:

------ Rebuild All started: Project: test, Configuration: Debug Win32 ------

Deleting intermediate files and output files for project 'test', configuration 'Debug|Win32'.

Running xiilink manually from the command line generates:

I assume that this is something to do with path variable settings of some sort, but I cannot figure out which. Suggestions?
