cp/constexpr.c change needs gengtype update?

[Andrew MacLeod]

Just updated to trunk and I have a compilation error:
/gcc/2014-10-14/gcc/gcc/cp/constexpr.c:3391:29: fatal error: 
gt-cp-constexpr.h: No such file or directory
 #include "gt-cp-constexpr.h"
                             ^

I presume its due to :

2014-10-15  Paolo Carlini  <paolo.carl...@oracle.com>
       * constexpr.c: ... here, new file.

with no gengtype update to create the file...?

or am I missing something else?
