[llvm-dev] I'm having problems compiling a program. Please help.

[Michael Kruse via llvm-dev]

Visual Studio comes with a batch file vcvarsall.bat that sets the
environment variables containing the paths to headers and libraries.
You can select the environment from the start menu, e.g. "Developer
Command Prompt for VS 2019" or "x64_x86 Cross Tools Command Prompt for
VS 2017".

If not, where can I get them?  I don't want to install Visual Studio because (to my understanding) it's proprietary software. I've included the program I'm trying to compile (hello.c) below.
