Of course they didn't. But knowing that linkers restricted the
identifiers' length to 6 chars, it made sense for preprocessors
to restrict them as well before passing them to the compiler
and linker.

Actually, it's a bit more complicated than that, but the basic
restriction came from the linkers, the preprocessors only inherited
it.
