| This means that the unknown character is no longer ignored, despite the |
| comment. As a side effect a line starting with a line comment character |
| not followed by APP in NO_APP mode now triggers an error instead of just a |
| warning, breaking builds of glibc on m68k-linux. Earlier in |
| read_a_source_file where #APP is handled there is another comment that |
| claims that unknown comments are ignored, when in fact they aren't (only |
| the initial line comment character is skipped). |
| |
| Note that the presence of #APP will mess up the line counters, but |
| that appears to be difficult to fix. |

| * read.c (read_a_source_file): Ignore unknown text after line |
| comment character. Fix misleading comment. |
