Subject: [patch, libfortran] Fix PR 23598, iostat handling after library error

This is the reason why the original test case from
http://gcc.gnu.org/ml/fortran/2005-08/msg00307.html failed.

Regression-tested on mainline.

OK for mainline, and for 4.0 once I've regression-tested it there?

	PR libfortran/23598
