Is this a "new" version of xlf90? The code in question has been the same
for some time, and has been tested on AIX/xlf90 without seeing this error.

I would recommend just commenting out this line: since these are intrinsic
functions, it should not be necessary to have this line. Or, you could just
remove the "_REAL_" part of the line in evb_vars.f.

It is odd that xlf90 says "Type is ignored", but still treats this as an error
rather than a warning.

Other AIX experts may be able to pipe in here.
