Chibil: A C compiler targeting .NET IL

Chibil is a C compiler written in C# that compiles C code to .NET IL (MSIL) and generates COFF object files compatible with Microsoft's Visual Studio linker, demonstrating sufficient capability to run complex programs like DOOM. The compiler uses Visual Studio's link.exe for final executable generation and supports debugging features like line numbers and local variables in .NET debuggers, though it currently lacks a full standard C library and has limited support for consuming compiled code from other .NET code.
