ACAP uses STL, exceptions, and threads, extensively, and works fine under g++ 2.8.1; not so, under EGCS's g++. A number of people have reported many compilation problems with EGCS, though admittedly some of those reports predate 1.1.1 (up to you to convince these people to retry). I personally dislike EGCS because it requires that you build the compiler's libgcc.a so that it *either* _requires_ libc_r, *or* it *cannot* use libc_r. In other words, you get to eat threads overhead on all programs, or you don't get to use threads at all. A nice, binary switch that has to be flipped in one direction or the other. I talked about it this weekend with Mike Stump, the former maintainer (he's left Cygnus for Wind River Systems; seems there's more money in non-GPL'ed software...). I'm sending Jeremy Allison's patches to FSF libgcc.a into Cygnus, labelled as such, but I don't hold out much hope, since the major GPL'ed OS has kernel threads by default (the implementation model used is a mistake, but I've railed on that before...).
