Thanks for that Pierre, and thanks for the work you've put into it. I 
don't know whether I'll be any use for fixing any of the remaining 
issues, but will make a point of getting it onto one of my development 
systems.

I'm told that Lemote is starting to make server-style boxes (8 cores, 
16Gb) but price isn't known yet.

When I started comparing the FPC source with the unofficial MIPS fork on 
Sourceforge, I was hoping that I'd be able to make some sense of what 
was going on and document it. I think that Paul Robinson approached a 
potential zSeries (IBM mainframe port) with the same intention
