Bootstrap the build tool once and it will rebuild itself as needed:

cc -march=native -O3 build.c -o build

or:

md out & cl -nologo -std:c11 -O2 -Fo:out\ build.c

Then run the build tool:

./build

Pass the build tool the --debug flag to get a build suitable for development/debugging:

./build --debug

Debug builds enable dynamic reloading of almost the entire program and you can make changes to most code and recompile without exiting the application.

MSVC is not the target compiler for this application. While some attempt is made to keep an exe building with MSVC no effort is spent testing that it works beyond launching and running. Some previous attempts at testing it have indicated that MSVC is miscompiling parts of the code. Additionally there have been valid (as far as other C compilers are concerned) lines of code in this project that have caused MSVC to crash during compilation. If your compiler is so poorly written that it crashes on ANY input is it really worth our effort to support?
