The _M_IX86 is not defined.

However, I am actually less concerned about whether or not Boost.Context 
is functional on WinCE/ARM.  What doesn't seem right is that 
Boost.Context is aborting the entire regression test sequence by 
generating a run-time error in the jamfile.  I would expect that if 
Boost.Context does not know which asm files to build for a certain 
platform, then it would fail gracefully and allow the regression test 
script to move on to other tests for other libraries.  At the moment, 
the VeecoFTC regresssion tester is now unable to reliably test any 
libraries because of the way that the Boost.Context jamfile handles this 
problem.

Thanks,
