Few small fixes for Visual Studio builds
Hi,
This attempts to fix building with Visual Studio on the main
branch:
- Avoid returning a value in a
void
-rettype function. - Include needed system headers.
On the same line as this, are there any improvements suggested for !6114 (merged), since that would also help the CI catch issues like the ones here, since the Visual Studio CI job builds GLib as a subproject.
With blessings, thank you!
