compilation error: expected expression when handling typeconv.cpp on mac

Reporting a bug

• I have tried using the latest released version of Numba (most recent is visible in the change log (https://github.com/numba/numba/blob/main/CHANGE_LOG).
• I have included a self contained code sample to reproduce the problem. i.e. it’s possible to run as ‘python bug.py’.

Code

I build numba main branch code on my x86_64 mac machine, but get a compilation error.

Given I guess this issue has been fixed by https://github.com/numba/numba/pull/8389, close it now.
