Ping ** (2./7.) Fix PR 92004, restore Lapack compilation

[Thomas Koenig]

Hi,

this patch fixes an overzealous interpretation of F2018 15.5.2.4, where
an idiom of passing an array element to an array was rejected. This
also restores Lapack compilation without warning.

Regression-tested. OK for trunk?

Would it be possible to get a speedy review on this?  I'd like to get
this working again as soon as possible.

Regards

        Thomas
