[Oberon] A2, targeting a Geode SC3200.

[Felix Friedrich]

Dear Peter,

(a) TARGET="AMD" is correct, it translates to -b=AMD compiler options 
(which is the default)
(b) compiler option --useFPU is correct when there is no SSE available, 
but then you need also to replace the runtime modules XMM.I386.Math.Mod 
XMM.I386.MathL.Mod by  I386.Math.Mod I386.MathL.Mod in Release.Tool. 
Unfortunately this is not prepared as a build-option so you have to do 
it manually.

Regarding your comment w.r.t language: I agree, it sounds a bit dodgy.
We are a small community with only little manpower. Best would be if 
everyone in the community would provide fixes of this kind him/herself.
Please register for an ETH account as described at 
http://trac.inf.ethz.ch/trac/lecturers/a2, inform me about this per 
email and I will provide you write access rights.

For more difficult problems or real bugs we now have the bug tracker / 
tickets at http://trac.inf.ethz.ch/trac/lecturers/a2

Regards
Felix
