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