Does it actually reach the goal? IOW is the sourcecode (+ whatever you do with the libs) smaller than the compiled binary? My gut says that C is not expressive enough to make it a space efficient scripting language

Yes, but a single deployment (exe+dll) will be larger. Only multiple compiled files will actually save something. This due to unused code (by this program) in the DLL, and the DLL glue code itself.

Same goes for memory. If the DLL can't be shared in memory (and page out unused sections), the memory footprint of running multiple binaries will be larger in the memory.

Small hello world is pointless in a dos forum, as there is always the hard to beat "echo" in the command interpreter. @echo<space> has 6 bytes overhead.
