Hi Steve,

s/previusly/previously


Fixed, committed. Thanks for the review!

Do you it gfortran should skip the front-end optimization pass
if error(s) have already been reported?  On entry ito this pass,
you could test for the error count and simply return.


I thought about this for doing this here.  It's a front-end pass,
but for error checking and warnings, not an optimization one, so
I thought throwing a few additional errors / warnings would not
hurt.

Regards

	Thomas
