I saw once some C code where a comment before start of a function said:

"Too large for a macro"

Later I learned that the programmer did everything in macros, and
only if they could not, resorted to functions.
 
The most fun was when seeing a macro using other macros. (some C
compiler would chock on this).

Saw one C file which had 7 different compilation modes, and overlays between
them. So complex, impossible to understand one mode from the other becuase
every other line there is an #ifdef this_mode || that_mode, so the only
way to understand the logic of each mode by itself, is to compile 
using -E flag (with one -Dmode_name) and then look at the outout of 
the pre-processor.  one mode did not compile at all, it was missing 
header files. Later I learned this mode was no longer supported (so dead code
sitting in there).

One of the things I like about java (as with Ada) is lack of macros
and pre-proccessor and everything that comes with that (i.e. the #define mess),
and lack of header files.
