I've managed to get w3 compiling with vs2019 but there were a couple of adjustments that needed to be made.
First there was the matter of string concatenation. In a few places through the source there are instances where #define STR "s" are concatenated with literals "x"STR"y"... I think this clashes with some of the more recent developments with how C++ extends literal suffixes. It's easily fixed by just inserting some spaces.
The next issue I ran into was the linker complaining about sprintf. Apparently after vs2015 this was all gutted out and put into legacy_stdio_definitions.lib. It's fixed by just adding this to the linker input for the projects that complain. This doesn't fix the complaint about __iob_func. For that I had to add FILE _iob[] = { *stdin, *stdout, *stderr }; extern "C" FILE * __cdecl __iob_func(void) { return _iob; } to loadpng.cpp.
I'm happy to report the tool runs fine, Afterburner reports a whopping 2300fps in the main window. They don't write code like they used to! Hope this saves someone 20 minutes.
