+
+/* This is a simple minded program that tries to find illegal macro
+   definitions in system header files. Illegal macro definitions are
+   those not from the implementation namespace (i.e. not starting with
+   an underscore) or not matching any identifier mandated by The
+   Standard. Some common macro names are considered okay, e.g. all those
+   beginning with E (which may be defined in <errno.h>) or ending in
+   _MAX. See the arrays prefix[] and suffix[] below for details.
+
+   In a compliant implementation no other macros can be defined, because
+   you could write strictly conforming programs that may fail to compile
+   due to syntax errors: suppose <stdio.h> defines PIPE_BUF, then the
+   conforming
+
+   #include <assert.h>
+   #include <stdio.h>      <- or where the bogus macro is defined
+   #include <string.h>
+   #define STR(x) #x
+   #define XSTR(x) STR(x)
+   int main (void)
+   {
+     int PIPE_BUF = 0;
+     assert (strcmp ("PIPE_BUF", XSTR (PIPE_BUF)) == 0);
+     return 0;
+   }
+
+   is expected to compile and meet the assertion. If it does not, your
+   compiler compiles some other language than Standard C.
+
+   REQUIREMENTS:
+     This program calls gcc to get the list of defined macros. If you
+     don't have gcc you're probably out of luck unless your compiler or
+     preprocessor has something similar to gcc's -dM option. Tune
+     PRINT_MACROS in this case. This program assumes headers are found
+     under /usr/include and that there is a writable /tmp directory.
+     Tune SYSTEM_INCLUDE and TMPFILE if your system differs.
+     #define BROKEN_SYSTEM if system(NULL) bombs -- one more violation
+     of ISO C, by the way.
+
+   OUTPUT:
+     Each header file name is printed, followed by illegal macro names
+     and their definition. For the above example, you would see
+     ...
+     /usr/include/stdio.h
+     #define PIPE_BUF 5120
+     ...
+     If your implementation does not yet incorporate Amendment 1 you
+     will see messages about iso646.h, wctype.h and wchar.h not being
+     found.  */
