My recent patch to change the error format to include the file name and unit 
number may be the culprit.  This touched on gfortran.h so you may need to 
bootstrap and see if that fixes it.

If not, I will work with you to sort this out.

error_format is a new test case that went with the patch.  read_comma I never 
encountered a problem with.
