He says that cccp (the GNU C Compatable Compiler Preprocessor) doesn't

This is quite correct, and documented behavior.  In fact, gcc comes 
with directions on how to make an ioctl.h file that works.  The reason
for this behavior is the ANSI Proposed standard.  It dictates that 
macro expansion NOT occur within quote marks.  Instead, strinification
and concatenation preprocessor operators are provided.  Take a look
at the info file that comes with gcc.
