[libunwind] libunwind in gcc

[Tommy Hoffner]

Sorry, if this is slightly of topic.

Does anybody know the current status on gcc concerning libunwind. There 
was a message regarding --enable-libunwind-exceptions (is it a command 
line option?), which i can't find in the documentation for gcc 3.3.3 or 
3.4.2.

What I'm specicially interested in is support for libunwind in the c++ 
libraries (i.e. using libunwind when handling throw/catch).
Is it in there? from which version? is it default behavior (i.e. is it 
likely to be turned on in prebuilt packages like debian libstdc++? or am 
I expecting way to much :-)
