Thank you.

This is the expected result, and it is the default now.
It seems I misread and thought that the warning would have been issued even if that option was given.
Could you try the latest snapshot (or master branch)?


----------------------------------------
Bug #20904: 3.4.0-preview2: Building miniruby.exe fails for mswin32
https://bugs.ruby-lang.org/issues/20904#change-110930

* Author: jun66j5 (Jun Omae)
* Status: Open
* 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
```
