[libxml++] What is behind LIBXMLCPP_EXCEPTIONS_ENABLED and the removal of exceptions?

[<Lukas Orlowski dlr de>]

Hello there

I have just recompiled my code against the latest gtkmm libs on WIN32
and on linux and I was confused to see it crash.
The segfault occures when ever an exception should be thrown. 
Please explain what the idea behind the usage of the
--enable-api-exceptions flag is (which was disabled for my binary
release).

Regards
