Looks like "putchar" is inlined [1]. That means the "putchar" you're

I don't know why it was done this way. Perhaps it's just a macro on some
platforms.

It is a macro on some platforms, and that's why it was done that way in
core.stdc.stdio. These days, however, it is better to replace such
macros with a template. That way it will not be necessary to link with
druntime.
