Like this?

/* Coccinelle only does limited parsing of headers, and chokes on some idioms
 * defined in compiler.h and queue.h.  Macros that Coccinelle must know about 
 * in order to parse .c files must be in a separate macro file---which is
 * exactly what you're staring at now.
 * To use this file, add the "--macro-file scripts/cocci-macro-file.h" to the
 * Coccinelle command line.
