> As it is mentioned in the UG-5.3.0, "Also, compilers that do not support
intrinsic calls flush, get_environment_variable,get_command_argument,
command_argument_count are no longer supported since v.5.2.1.", the old
compiler complains about "internal error" which most probably is due to the
above-mentioned calls present in "exx_X.f90" routines in the CP package.

This is very unlikely, there are no calls to those intrinsic functions in
EXX, and even if there were, they wouldn't cause an internal compiler
error. Upgrade your compiler or ask your system administrator if you
cannot.

For others there is no problem.
