***** purpose of patch3.6.1.tar.gz *****

(i) The direct control of optimization level by applying 
#pragma optimization_level 1 to
 
EigenBand_lapack.c
Eigen_lapack.c
Eigen_PHH.c
Eigen_PReHH.c
XC_PBE.c

(ii) Correction for the use of '-Dnoomp' and/or '-Dnompi' to 

exx.h
exx_debug.c
exx_file_eri.c
exx_file_overlap.c
