I did that because I wasn't sure if it would work on mipsel straight out
of the box, since the endianess is important for I/O among other
things.

I'm not sure how to understand your table. Could you, along the lines
outlined at
http://wiki.debian.org/DebianScienceROOT -> Porting Notes
tell me what changes would be needed? Perhaps which already support
registers the 6 cases above would be similar to?
I guess the O32/N32/N64 is the "word-size", but what is the "O" and
"N"?
I don't know what you mean by ILP32/LP63. I also don't know how to deal
with "long long" in 1 or 2 registers.
I guess the "argument registers" refers to variadic arguments, but
exactly what that would imply in the ROOT source code I don't know.
I've Cc'ed this mail to rootdev and cintdev for more input.

OK. That goes for the return from `uname'?

Great. Could you make the packages publicly available? If so, I'll
upload them to the above repository.
Thanks again for your help.
