Thanks.
I also tried cross-compiling on Debian GNU/Linux sid with:
* Meson: 1.5.0
* MinGW-w64: `x86_64-w64-mingw32-gcc (GCC) 13-win32`
* Zstandard: dev
`target_x86_64-w64-mingw32.meson`:

It didn't reproduce this problem. (`libzstd.dll.a` doesn't have `wcrtomb`.)
The diff between my build log and the attached verbose build log show that
`-pthread` is used with Yggdrasil.
It's related to
https://github.com/facebook/zstd/commit/5be2a8721d527ae349539b459b35fb628467e00d
. So I also tried Zstandard 1.5.6 that is used by Yggdrasil.
The `-pthread` diff was disappeared with Zstandard 1.5.6 but this problem
wasn't reproduced. (`libzstd.dll.a` doesn't have `wcrtomb`.)
MinGW version may be related. It seems that Yggdrasil uses 4.8.5. Can we try
newer MinGW-w64 in Yggdrasil?
