It looks like there are a lot of changes to how argc/argv are generated by different gcc versions.

I also have perls 5.36.0, 5.38.0 and 5.40.0 built using MS Visual Studio 2022.
All of those perls suffer the very same issue: 
D:\comp-2022-vs>perl -le "printf(""" wtf""");"
Can't find string terminator '"' anywhere before EOF at -e line 1.

D:\comp-2022-vs>perl -le "printf("""wtf""");"
wtf

So I think it's probably a case of the mingw C runtime having only recently "caught up to" (and synced with) something that has been present in Microsoft's C runtime for quite a while.

The fact that it's something that MS toolchains do, pretty much legitimizes the change in behaviour.
Maybe someone will alert MS to the change, and they might do something to revert it.
But it's something that's only going to be noticed when using """ ... and who does that, anyway ?

Cheers,
Rob
