Thanks for the fix!

Weird. I get the warning on the following environments:

* Windows Server 2022 (10.0.20348) on GitHub Actions
  - Visual Studio 2022 Developer Command Prompt v17.12.0
  - Windows SDK: 10.0.26100.0
  - See:
    - x86: https://github.com/jun66j5/ruby-build/actions/runs/11993783074/job/33435109634#step:4:638
    - x64: https://github.com/jun66j5/ruby-build/actions/runs/11994220038/job/33436008633#step:4:1482
* Windows 10 22H2
  - Visual Studio 2022 Developer Command Prompt v17.12.1
  - Windows SDK: 10.0.20348.0

I noticed C4013 warnings for `_finitef` only for x86 by adding -w24013 flag at https://github.com/jun66j5/ruby-build/actions/runs/11993783074/job/33435109634#step:4:580:

```
D:\a\ruby-build\ruby-build\ruby-3.4.0-preview2\vm_insnhelper.c(6432): warning C4013: '_finitef' undefined; assuming extern returning int
prism/static_literals.c(504): warning C4013: '_finitef' undefined; assuming extern returning int
prism/prism.c(4153): warning C4013: '_finitef' undefined; assuming extern returning int
```

Checking ucrt/corecrt_math.h, the `_finitef` seems to be available for x64 but not x86.

Bug #20904: 3.4.0-preview2: Building miniruby.exe fails for mswin32
https://bugs.ruby-lang.org/issues/20904#change-110743

* Author: jun66j5 (Jun Omae)
* Status: Feedback
* Backport: 3.1: DONTNEED, 3.2: DONTNEED, 3.3: DONTNEED
----------------------------------------
I tried to build 3.4.0-preview2 with MSVC x86, however linking miniruby.exe failed with the following eror:

```
linking miniruby.exe
   Creating library miniruby.lib and object miniruby.exp
win32.obj : error LNK2019: unresolved external symbol _GetSystemTimePreciseAsFileTime referenced in function _clock_gettime
miniruby.exe : fatal error LNK1120: 1 unresolved externals
```

It doesn't fail with MSVC x64.

Investigating it, Windows 8 is required after #20563 but `NTVER` is still `0x0600` in `win32/Makefile.sub`. I think it should be `0x0602`. Workaround is to invoke `win32\configure.bat` with `--with-ntver=0x0602`.

Also, adding temporarily `-w24013` to `WARNFLAGS` in `win32/Makefile.sub`, the following warning is received.

```
compiling win32/win32.c
win32.c
win32/win32.c(4789): warning C4013: 'GetSystemTimePreciseAsFileTime' undefined; assuming extern returning int
```
