Changes in default exception handling?

[Leif Ekblad]

In the new snapshot (20060114), there seems to be changes
to default exception handling in C++. When I tried to build libstdc++-v3 
with the last configuration, the compiler complains that no
exception method is specified. This problem is solved by giving
--enable-sjlj-exceptions option to configure. Is there a way to
specify this as a default for an OS, so you don't have to give
this option at configure-time?
