I am willing to chalk it up to suboptimal compile flags...I know my
way around GCC's options, but I'm not an expert in that area.

The example I cited is a real-time image processing application. It
transfers video frames over the network and processes them in memory,
performing various spatial algorithms such as convolution and
averaging. The frames are usually around 300KB in memory. It is
written to be as cache-friendly as possible on the target platform. It
is UltraSPARC-specific, as some of the libraries use the VIS
instruction set (a SIMD implementation found on UltraSPARC processors).

I will make some time to do that.

No, just the opposite...I'm a C guy, no C++ here. But thanks for the
advice anyway. :-)

I was surprised too...I've always been accustomed to it building
cleanly on many platforms.
