[Pw_forum] mpif90 compiler that uses ifort

[Ahmad Yassin]

I found that I can use OpenMPI with Intel compilers without recompiling
it... just by setting the environmental variables OMPI_CC=icc,
OMPI_CXX=icpc, OMPI_F77=ifort, and OMPI_FC=ifort . I'd be sure when doing
the ./configure to set CC=icc, CXX=icpc, FC & F77 = ifort... Thank you all a
lot...
