|    #   define DEBUG printf
|    #else
|    #   define DEBUG(ignore)
|    #endif

without checking whether it worked.  Well it used to work back when
I was running on an old system, with an older preprocessor, but
nowadays on many preprocessors you get an error message about a
mismatch in the number of arguments when you have debugging turned
off.

Here I go, crawling into a cave and pulling the opening in after me...
