What I'm interested in is the broader policy: when reviewing patches,
if we encounter a foo() declaration, should we consistently request a change to
foo(void)?
If yes, the standard should be documented somewhere.
I think that they should be consistently fixed for the reasons mentioned in
[1], and that the best way to achieve this goal would be to enable
-Wstrict-prototypes
by default ([2]).
Yes, why not add -Wstrict-prototypes and perhaps -Wold-style-definition to
the standard warnings. Then we don't have to keep chasing these manually.
Yeah, I'll look at adding those.
I played with this a little bit. A problem I found is that the
generated configure code itself generates its test programs with
'main()', and so with these warnings, many of these tests will fail. So
you'd need to create some different arrangement where you test for the
warnings but only add the flags at the end of configure.
But also, my research indicates that -Wstrict-prototypes and
-Wold-style-definition are available in all supported gcc and clang
versions, so maybe you could avoid this problem by not testing for them
and just unconditionally adding them at the end.
