It's a left-over from RTT 1.x. See
http://people.mech.kuleuven.be/~orocos/pub/stable/documentation/rtt/v1.12.x/doc-xml/orocos-installation.html

for a short description. It's unlikely you want to turn it on, since
most Boost code we rely on requires exceptions, unless Boost fixed
this again in very recent versions.
