[Wien] Error: undefined symbol: __intel_cpu_indicator

[Peter Blaha]

I just experimented today with the latest free ifort version (on an P4emt 
system with SUSE 9.3).

using -i-dynamic   and running lapw1c I got exactly the error message 
above.

It can be avoided using 
       -static-libcxa
              Links the Intel libcxa C++ library statically. This option 
              is the opposite of  -shared-libcxa.
(which is from the most recent "man ifort")

The ifort release notes also state, that depending on the memory-model 
(medium or large) -i-dynamic is necessary and -i-static would not work properly.
(Nice that it still links without error, but crashes later.

Thus I would recommend (on em64 systems) NOT to us -i-static.
