No.  The fun part (let say not before January) will be to make the 
inline-threaded engine functional on ARM.

For the benefit of all subscribers: I am currently making the *final* little 
modifications to my thesis (as requested by the Ph.D. committee; little 
typos...) which I should be publishing on the Internet in a few days.  Yep,  I 
have successfully [:-)] passed both the written Thesis evaluation and the oral 
Ph.D. defense.

I don't know for sure, but I think it is internally generated by GCC.  I looked 
through config.guess and found:

#if defined (__arm) ...

You might want to try that, just in case it works. ;-)

Otherwise, we can play tricks in configure.ac (as long as the configure magic 
correctly detects ARM), and add a test to define a constant when ARM 
architecture is detected.
