Stefan is correct.  The preprocessor is not a compiler; neither is the
linker.  And there was not a c->Assembler and assembler - every C
compiler I know of (at least since the mid 80's) generated machine code
directly, although most did have the option to output the assembler
code, also.   There was not a separate assembler step.

And yes, the compiler is a one-pass compiler.  It does not allow forward
references.
