Package: cproto
Version: 4.7x-1
Severity: normal
Dear Maintainer,
If you dget src:tgif 1:4.2.5-2 and run
cproto -{P,F,C}"int f(a, b)" exec.c
you'll get a dump of the prototypes.
If you run
cproto -a -{P,F,C}"int f(a, b)" exec.c
you'll instead get a lot of output,
/some/ prototypes changed,
but that output ends with
exec.c:10428: syntax error at token ''
with the transformation edge at

exec.c starts by having 10427 lines,
so the error occurs one-past-the-end of that?
The compiler understands the code before and after the transformation
(so long as K&R declarations are allowed, of course).

I've reviewed the 4.7y-1 manual, and I think if I had it while doing the
tgif conversion I would not have felt the need to have opened the bugs,
which is equivalent to being fixed. Thus, closing; thanks.

Nor do I think this would be a good use of anyone's time, frankly.
