As far as processors go, I'd put them in this order: x86, ppc, sparc. I don't know how much Alpha is used, but I think it is quite used in the Linux world (it was for a long time Linus' preferred workstation). I don't know how the new 64bit extensions from AMD and Intel to x86 affect our portability and thus require special care. IN case they are probably now widespread enough to be put in this list.

FWIW, all of gnustep-core on Gentoo/Linux has been built and found to
work on x86, ppc, sparc, amd64, and alpha.  The only arch that
I/the-dev's-that-have-assisted have tried that hasn't worked quite
right yet is mips.

My personal experience is that -base is the hardest thing to get working for example between NetBSD x86, ppc, 68k, sparc... Most often it is not our fault: ffcall/libffi, linker and compiler issues were the most frequent problems I have experienced lately (and which David Ayers and Alexander Malmberg often helped me to pinpoint and solve...). Once those work, -base compiles and -gui and -back rarely are affected my CPU differences but only OS ones.

I really hope that all ffcall / libffi issues are cleared up befre any
"1.0" stuff goes on.  Since day 1 of me+GNUstep, FFI issues have been
the bane of my Stepping.  Whatever arch's and operating systems are
deemed "supported" should be compiled into a list describing whether
ffcall or libffi is suggested/supported.  Even better, we should drop
support for one, and then work to support the other on all platforms
GNUstep supports.  While I'm sure this would never happen here, my
vote would be for ffcall, as I realize: it actually has up to date
documentation -- http://www.haible.de/bruno/packages-ffcall.html  .
