[Wien] bandstructure calculation

[Masao ARAI]

Dear Prof. Blaha, Prof. C-W Zhang,

Recently I encountered similar error message.
It occurs because "tail" command in newer Ubuntu Linux (and possibly others)
invalidated the option +N.

https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/241555

Thus,  the following command emits an error message:

$ tail +3 case.irrepup_1
tail: cannot open `+3' for reading: No such file or directory

According to above web page, this problem can be avoided if the 
environment variable
_POSIX2_VERSION is set:

$ export _POSIX2_VERSION=199209
$ x spaghetti -p

I am not sure whether this environment has  any side effect.
But, if I set it before execution, spaghetti (with parallel execution) 
works fine.

Best regards,
