Well, it would be possible to use :c:expr: with Sphinx 3.2.1,
in order for it to check for invalid C declarations.
Btw, this is one of the improvements over the last versions: the
rewritten C parser there is a lot more pedantic with regards to the
C syntax.

That's said, the backward-compatibility code I added at
Documentation/sphinx/cdomain.py will convert this into a
literal markup though, as there's no equivalent tag before
Sphinx 3.x.
As there are still one upstream issue on Sphinx 3.x that requires a fix[1],
and we don't know yet the issues with :c:expr[2], at least for now, I would
avoid adding :c:expr: markups.
[1] Right now, the C domain is not able to have two names
for different types. So, it is not possible to have
a struct "foo" and a function "foo".
Due to that, while I was able to fix all warnings with
Sphinx 2.x build, Sphinx 3.x will still have bogus
warnings.
[2] One of the limitations of :c:expr: is with regards to function
prototypes. You can't use it like: :c:expr:`int foo(void);`,
as it will complain with the function return type.
