Nick's advice to upgrade my compiler is
timely (I'm using GCC 2.96 from
RH 7.2) but unfortunately I can't make the switch right now. If there's
an obvious (or non-obvious) solution to my dilemma I'd be happy to hear
of it.
Its possible to installed the redhat provided gcc3 alongside 2.96, you set
some environment variabel to set which one youre using. You have to make
sure that all the C++ it links against is built with the same compiler
ofcourse.
