-/* 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.  */
