>Description:
There is an invalid trailing comma in the "good" example of Rule 6 of the libc++ style guide, located online at:
http://gcc.gnu.org/onlinedocs/libstdc++/17_intro/C++STYLE

enum { name, }; is not currently legal C++, although it was made legal for C99; and while g++ will compile it without complaint as a common extension, there are compilers, such as aCC on HP-UX 10, that will not.  The corresponding "bad" example in rule 6 is correct.

This is how the web page should appear; I am not in a position to provide the actual patch against the file CVS that the web page is generated from.

   {
     space = _ISspace,
     print = _ISprint,
-    cntrl = _IScntrl,
+    cntrl = _IScntrl  // no comma for last entry
   };
   -NOT-
   enum { space = _ISspace, print = _ISprint, cntrl = _IScntrl };
