[Wien] Regarding Wien2k parallel installation

[Laurence Marks]

What about CC ?

I used (bash)
export CC=icc F77=ifort
(Note, my mpicc and mpif77 are setup with ifort already.) Then:

./configure CFLAGS=-O2 -xHost -pc80 -no-complex-limited-range -mp1
-prec_div -no-fast-transcendentals -prec-sqrt --enable-mpi
--prefix=......

Please note, it is CC and F77 not cc, f77 -- the case matters. You can
check in the fftw directory with
grep -e "CC " -e "F77 " Makefile

Note, if by accident gcc and gfortran get used it is possible that
there are issues related to whether there is a "_" added at the end of
the name. There was a recent bug in gfortran on this.
