[Wien] x w2w error in WIEN2k.14

[Gavin Abo]

That error usually happens if the w2w executable file is compiled on a 
64 bit operating system, but then it is copied and ran on a 32 bit 
operating system [ 
https://www.dartmouth.edu/~rc/classes/softdev_linux/32-64bit.html ].  
You can probably use the Linux 'file' command [ 
http://superuser.com/questions/791506/how-to-determine-if-a-linux-binary-file-is-32-bit-or-64-bit 
] to check if the w2w executable file is 32 bit or 64 bit:

$ cd ~/WIEN2k.14/
$ file w2w

(where $ is a bash terminal)
