+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.
+
+Andreas.

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