Pathscale is not dead, in fact I'm talking to them more or less daily at
the moment. They have been restructuring since the demise of SciCortex
last year. I hope they will be able to release a new version fairly
soon.

In my opinion (working mostly with Fortran codes, shudder) it is the
best compiler around. Although they have had problems over the years in
coming out with fixes for bugs in a timely fashion.
