I think both MSVC and MinGW support this.
MinGW implementation seems to be dummy, so relevant only for MSVC. But should not break anything.

A better fix woul be to rewrite FileAccessWindows so it uses the Win32 API directly. However, this already brings value.
This is likely a better option.

This raises the number to the maximum value according to the docs, which is 8192. The default is 512.
This should avoid many file access errors that happen in big projects during heavy operations dealing with many resources.
