Error when building on Mac

[Zabrane]

The build is failing on MacOS:

$ sw_vers

Help appreciated.

I don't have a Mac anymore, so it's kinda hard to maintain the Mac port without breaking anything. Sorry for that

In the meantime, you can probably comment out the function call. Lwan should work without this.
