This is not part of the compiler at all, but part of the pre-
processor cpp.  They do not 'contain' anything, but are useful
MACROS (sometimes) for doing debugging.  Look at the assert(3) macros
for example (at least on the 4.1 bsd machines).  I believe this
was even around on some of the V7 cpp's.
