Scott -
You can still get ifc 7.1.033 through 7.1.040, but you may have to dink
around a bit with the downloads buttons on the intel premier support page to
see everything. You can also still get ifc 6 (listed as the full support
compiler, but it is all the same stuff; the difference in support is how
intel responds to any grief you might want to throw their way - really slow
vs. really really really slow), and that may be necessary for folks on
redhat 7.2 and earlier (I need to check out 7.1.033 on redhat 7.2; ifc
7.1.038 will tell you it is not supported, so I have not gone further with
it).
Regards - Bob
