 Not all :-).

 gcc apparently has a kludge to hide this bug.  It apparently looks at the
 names of the headers.  The following compiles with no warnings even with
 cc -ansi -pedantic:
 
 a.c:
 	char *malloc();
 	#include <stdlib.h>
 
 The following compiles with just one diagnostic with cc -ansi -pedantic:
 
 b.c:
 	#include <stdlib.h>
 	char *malloc();
 
 The output of the following still compiles:
 
 	cc -E b.c >c.c
 
 The output of the following doesn't compile:
 
 	cc -E -P b.c >d.c
