[bbv2] msvc toolset broken?

Whenever I build anything now with the msvc 7.1 toolset, I'm getting 
heaps of warnings like:

msvc.compile.c++ 
..\..\..\bin.v2\libs\xpressive\perf\msvc\debug\command_line.obj
command_line.cpp
C:\Program Files\Microsoft Visual Studio .NET 
2003\Vc7\include\ostream(574) : warning C4530: C++ exc
eption handler used, but unwind semantics are not enabled. Specify /EHsc

This didn't used to happen. What's up? How do I fix it? And why aren't 
exceptions enabled by default?
