Here's a CI run testing various strawberry perl versions on windows. I did
apply Victor's patch to make things at least compile on newer versions of perl.

https://cirrus-ci.com/build/6290387791773696
- 5.32.1.1: fails with "src/pl/plperl/Util.c: loadable library and perl binaries are mismatched (got handshake key
0000000012800080,needed 0000000012900080)"
 
- 5.30.3.1: crashes in plperl_trusted_init(), see "cat_dumps" step for backtrace
- 5.28.2.1: doesn't crash, but lots of things don't seem to work, particularly
  around error handling (to see regression diff, click on regress_diffs near
  the top, and navigate to src/pl/plperl)
- 5.24.4.1 and 5.26.3.1: pass

The 5.32.1.1 issue looks like it might actually a problem in strawberry perl
perhaps? But the rest not so much.
