That's what I meant by a "significant addition"...  bloating the binutils 
code by 20k just so maybe 30 people can use OpenXDK.  That's personally why 
I'd just use PE format then convert PE to XBE with another tool. 
Microsoft's and Xbox Linux's PE->XBE tool is named (independently) 
"imagebld"; OpenXDK's current poor design is named "cxbe".

Microsoft's game-developer-only tool uses link.exe with /subsystem:xbox to 
produce PE files for later conversion.  Try it on standard VC7.1, it works:
