Tiny Basic Downloader Builder (Proof of Concept)

This is not PHP code but C code. Also hardcoding the string locations is not really a good way to go as this will not be platform, compiler or linker independent. Win7 vs Win10, MSVC 14 vs 16, gcc vs MSVC, etc. One idea is to instead generate a symbol file e.g. PDB that contains the symbols with the string offsets, or at least search the file for the marker strings. 50 bytes for URL and path is ok for PoC but not practical.

The main purpose of this snippet is to try to build smallest! as possible working binary with MSVC compiler/Linker (GUI - API).
Also get (produce) a clean assembly to trace and understand easily!
It's a very basic PoC for only learning purpose.
