[Wien] errors during instalation.

[Gavin Abo]

The latest version of ifort (Composer XE 2011 Update 7) will likely not 
compile Wien2k correctly.  Try Composer XE 2011 Update 3 
(composerxe-2011.3.174), it seems stable for Wien2k.

The lapw0 error is probably because you need to change the compiler 
optimization flag to -O1.  By default, it might be -O3, which has been 
known to break code loops using ifort 12.

In the directory of Wien2k files, try the following command to rerun the 
installation in the terminal: ./siteconfig_lapw

Alternatively, you can type: ./siteconfig
- Selecting the O option should take you where you can check or set the 
compiler flag to -O1.

Also, try searching the mailing list archive 
(http://www.wien2k.at/reg_user/index.html) for similar discussions.

Hope this helps.
