That header is not missing, it became standardized, so use <numeric>
instead. The libstdc++ developers added a bunch of upcoming things into
the ext/ and tr1/ subdirectories in the past, but there is really no
need to use these anymore, these days.

It is really the other way around; the C++ support in clang 3.4 is more
advanced than the gcc 4.7 port. Clang 3.4 supports all of the C++11
standard, and some bits of the upcoming C++1y standard. According to
gcc's own status pages, gcc 4.7 "implements much of the C++11 standard",
and for gcc 4.8, "as of GCC 4.8.1, GCC's C++11 mode implements all of
the major features of the C++11 standard".
