  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.
