1.47 +This means that the unknown character is no longer ignored, despite the
1.48 +comment. As a side effect a line starting with a line comment character
1.49 +not followed by APP in NO_APP mode now triggers an error instead of just a
1.50 +warning, breaking builds of glibc on m68k-linux. Earlier in
1.51 +read_a_source_file where #APP is handled there is another comment that
1.52 +claims that unknown comments are ignored, when in fact they aren't (only
1.53 +the initial line comment character is skipped).
1.54 +
1.55 +Note that the presence of #APP will mess up the line counters, but
1.56 +that appears to be difficult to fix.
1.57 +

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