There's nothing really that odd about it. Back when C was designed it really
wasn't all that easy for compilers to do that (they didn't have much memory or
CPU to work with). It then was much easier for humans to do their part, as the
programs C was designed for weren't all that large.
The thing that is odd is that people still think C is a good language to use for
developing *today's* software.
