As an experiment, I have changed xpressive's regression test to not use 
Boost.Test. The results are perplexing. The runtime crash went away on 
cw-9_4 but remains on cw-9_5-darwin. I don't know about cw-9_6. It's 
possible that it has something to do with the fact that the 9.4 test is 
run on Win32 and the 9.5 test on Darwin. Is there is another header 
pulling in CW's buggy versions of unistd.h/signal.h/setjmp.h on this 
platform?

Can someone with CodeWarrior/Mac (any version) sync boost/xpressive and 
libs/xpressive and try running xpressive's "test1"? A stack backtrace 
would shed some light.
