Simple removal of those includes should be enough for the test purposes.
Ok, sure.

Too new C++ version for that test.

But I'm not sure what the test wanted to do.
I presume it just wanted to say that the function can throw an int - it's
probably not central to the test itself. I posted a patch to remove this
bit, and it was approved so I pushed this already.
Additionally, a UCRT build hits this error:
D:/a/_temp/msys64/gcc-mingw/bin/../lib/gcc/x86_64-w64-mingw32/14.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe:

_sys_errlist as a macro is available in stdlib.h for all platforms.
This change (untested) could fix it:

This does indeed seem to fix things, thanks! I'll send a patch with that
change, with your name on it.
