[Wien] errors @ wien2k_21.1 compilation

[Laurence Marks]

You have serious problems with how your computer/cluster is setup. These
need to be resolved for Wien2k to work, and for many other things as well.

The most obvious one is your locale, which you almost certainly cannot cure
by just using the -no-multibyte-chars flag.

You can look it up, but briefly, most code is written for the Latin
alphabet which fits into 256 ASCII code, i.e 1 byte. Computers can use
other alphabets, but these can require more than one byte. This can work
for some things, but many others can fail. I very much doubt that Wien2k
(including the parts for w2web, python and others) will work beyond English
or similar languages (French, German etc). It probably does not work with
Russian, Japanese, Chinese or Korean alphabets -- maybe someone can
confirm. What language is your computer set to?

I strongly suggest that you reset your computer/login to use a Latin
alphabet, when the LC_ALL issues should go away. In the process you will
probably update your OS, which will probably solve the memcpy problem,
which is perhaps due to messed up gcc libraries although it might be other
compile options.

A partial response.
