From: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
Date: Wed, 1 Apr 2020 00:13:11 +0200
Subject: Add preliminary VisualStudio support

 - Mostly workarounds/clutches in compat.h
 - Change getline return type to int
 - Replace C99 style flexible array with alloca
 - Add all the MSVC solution/project crap
