workaround patch
It's caused by reallocarray() added to glibc-2.26.
The problem is lack of #define _GNU_SOURCE (or any other
way to pull explicit prototype). Fixed upstream as:
https://github.com/westes/flex/commit/24fd0551333e7eded87b64dd36062da3df2f6380

There were a succession of further upstream commits now backported here. Noticed when doing some more Clang 16 work. This complements bec6a7be57fc3493dccef497b5d4b513c315f5f1 in that more effort is taken to ensure all necessary macros are defined so needed functions are available.
