From 636d56818a0d63a54acd7fd4added4343a204d92 Mon Sep 17 00:00:00 2001 From: Jay Krell Date: Sat, 11 Mar 2023 22:00:20 -0800 Subject: [PATCH] Port to Visual C++. - Combined nmake/Unix Makefile. - _alloca instead of variable size array. - Cast void* to char* for math. - C++20 for designated initializers. It builds.
