[Wien] A problem with icc and wien2k

[Laurence Marks]

I would check by hand your files (not using w2web). With some versions
of ifort/icc there are compiler bugs with overoptimization in sgroup
and/or symmetry. I would recommend using gcc rather than icc (the
difference in execution speed is neglegable, as the important code is
all fortran) then check the mailing list archive for the
overoptimization bug, I don't remember where it is.
