Correct, but I wouldn't quite put it that way.
The syntax of the C preprocessor is intimately related to C syntax.
In fact, it's part of it. It's a part that's quite different
from the rest of C's syntax (for example it's line-oriented
vs. token-oriented), and it's described in its own subsection of
the standard, but it's still part of C.
A macro definition must be on one logical source line (N1570 6.10p2).
The only way to form a logical source line from multiple physical
source lines is by using the \ continuation character (5.1.1.2,
translation phase 2, line splicing).
