[issue20381] Argument Clinic: expression default arguments broken

[Zachary Ware]

Zachary Ware added the comment:

This also prevents a vanilla trunk build (as of 85710aa396ef) from succeeding at 'Tools/clinic/clinic.py --make':

Error in file ".\Modules\_sre.c" on line 574:
Unsupported expression as default value: 'sys.maxsize'

I think the only reasonable check we can do is to make sure there aren't any syntax errors in the default value (see patch), but there may well be something I'm missing here.
