Well really simple:
I want to compile for my Pentum 4 and not a WIN32 Console App.
What tag/thing would I use for this?

Ok sorry after some readin here's more:
There are things in an os that open the console window n stuff (Stubs?)
I want to make a portable app (have a painfully handcoded way to tell what os the person has at runtime.)
Is there a way to stuff these things into the exe?

Not like I think you mean. Operating systems all have various approaches to the low-level details (ABI) and the system-provided functions (API), which generally means you have to compile your code separately for each platform you want to target.
