For the record, there aren't supposed to *be* any comments in
#NO_APP mode; just strict formatted assembly code and #APP of
course.  That's what it means.

If the glibc __sec_comment kludge is the problem, let me mention
that different patches have been sent to glibc in order to make
its kludge work properly(!) at least one that adds #NO_APP and
I'm sure would work, but it seems none have been applied.

Of course, we could do something that lets glibc emit its
.gnu.warning.* sections without assembler warnings, and avoid
using the __sec_comment kludge where the new thing is supported.
