jc1 doesn't seem to be able to process things from stdin.
The lexer seems to see errors when processing perfectly valid
Java code.
>How-To-Repeat:
After the patch above is applied, with:

  echo "class bar {}" | ...../jc1

We get:

  stdin:1: Can't open file - java_display_line_col

Because jc1 finds an error and wants to report it. The
way we report errors should be fixed when the input is stdin,
but jc1 shouldn't report an error in the first place.
