I will quote the email referenced:

C++11 code using isinf and isnan continues to compile after that
change, because the C++11 standard library provides its own versions
conforming to the C++11 requirements. However, the C++11 library
doesn't provide isinff, isinfl etc. and so code using those
(non-standard) functions will no longer compile if they are not
declared by glibc.

This was not clear to me, what kind of build issue are you seeing now?
Using isinf{f,l} by including just <cmath> along with C++11? If it is the
case please open a bugzilla (or update the original) and please commit
the fix.

if the change hasn't seen a release yet, then we can just re-use the
existing bug since it's really just a direct follow up to that ?

I do not see why not.

Hi, what's the status of this then - do we need to add a testcase or
can it be committed for 2.23? (or wait for 2.24?)

FWIW it's already in the Fedora glibc 2.22 package.
