* Match build-windows.bat changes
The location for manual setting of the vcvarsall.bat location moved to line 38 in the latest change.
* Update flags for clean x64/x86 building
std:c11 is required for initialization features used in raylib. UTF-8 for consistency in contemporary systems. /W3 gets rid of puzzling slack byte and linker in-lining warnings. /sdl for some insecure library usages in the user code that beginners should learn about early.
* 2021-10-01 core_basic_windows.c adjustment
1. The press F6 message and the placement of the compiled executable statement are incorrect for the scripts case.
2. <raylib.h> because "raylib.h" is meaningful only when compiling inside raylib/src/ folder.
3. main(void) to get rid of a novice-confusing warning.
