I suspect there are.  It is a bit of an unexplored corner, since as 
'raise' wasn't in 7th Edition Unix, so old code didn't use it.

Maybe uClibc on the ARM?  See, for example:

<http://osdir.com/ml/lib.uclibc.buildroot/2006-10/msg00139.html>
<http://svn.exactcode.de/t2/branches/6.0/package/base/uclibc/arm-raise.patch>

How about this more-conservative idea: Keep the raise module, and
blindly assume the existence of 'raise' elsewhere.
