Can you, though?

Compiling that source on Windows using visual studio produces a 98K executable.

You just need to add some compiler options; /MD should get the size down quite a bit already, then decrease the file alignment and merge sections together:

    /MD /link /align:4096 /filealign:512 /merge:.rdata=.text /merge:.data=.text

That produced a 1.5K binary, which with a custom stub should reach 1K.

So the point is moot, you can't have a simple 1k C example.

Have you actually tried this? Merging .data into .text doesn't work. The binary doesn't run and there's this link warning:

> LINK : warning LNK4254: section '.data' (C0000040) merged into '.text' (60000020) with different attributes

In order to get that to 1Kb you would probably have to drop the `.idata` section and resolve syscalls from the PEB like I did.
