My understanding is that this is because the version of vxworks that we are using is ancient, and WindRiver has essentially dropped support for it. It does what NI needs for Labview, so there is no reason for NI to upgrade.

971 has been running a modern version of GCC for a while now, and has seen no issues that can be traced back to the compiler. We have been using 4.5.2 for a while, but are in the process of upgrading.
