I'd recommend asking there first if you want to help.

I don't do IRC.
Also, I don't claim that "I want to help".

However, if I was aware of some issue that they're facing, with which I beleieved that I might be able to help, then I would most certainly provide that help.
If the issues are all with the operation of the "ecosystem" then that probably counts me out ... though I wonder that they have not yet been able to patch/replace that ecosystem with something that they can work with.

It's likely that the only things I could help them with are:
1) Updating to a later version of the 64-bit and 32-bit gcc toolchains and mingw runtimes - for which I'd just point them to the ready-built toolchains at https://winlibs.com/ that I've been successfully using to build perl and perl extensions for about the last 8 months;
2) Building the C libraries that ship with Strawberry - most of which I've built in the past, and some of which I continue to regularly build;
3) Building problematic "vendor" modules;
4) Building perl itself - though I doubt that's an issue as, these days, perl builds straight out of the box on Windows.

But, AFAICT, they're pretty intent on keeping their cards close to their chests, and that's about all I know.

Cheers,
Rob
