Research direction
Investigate why Visual Studio's stdio.h is not found. Check if the INCLUDE environment variable is set correctly or if the build script needs to load VS environment variables. Examine the generated command line and ensure cl.exe can find standard headers. Consider adding documentation for setting up the build environment on Windows.
