I wrote it yesterday, and spend today fixing all the sloppy code in the test suite with bad formats, and submitting PRs for projects with bad formats.

Unfortunately, Rainer says that Microsoft VS doesn't support the printf `z` specifier (despite it being standardized in 1999) in versions before 2015.

Is it time to throw old VS support under the bus?

We couldn't use clang-cl for this?

I've been advocating that for years, due to the MSVC 2015 runtime finally featuring near-complete C99 standard compliance and thus vastly simplifying portability and rendering previous workarounds and test special cases in druntime/Phobos obsolete. LDC has been requiring MSVC 2015+ for years.

That said, Rainer went to great lengths to maintain support with pre-UCRT due to the ease of redistribution (bundling 1 DLL vs. potential UCRT Windows component installation), so dumping it now just because of `%z` seems excessive to me.

As long as Optlink and DMC's std lib go with it.
