C++0x, V7R3, ixlc

Trying out some stuff on V7R3 and ixlc. Notice that I am coding a double
vector thusly:

vector<vector<int>> v2;

Under an older compiler, you'll get barked at for not spacing ">>" like ">

". I compiled with :

ixlc -+ -oBEAK/XXX -qlanglvl=extended0x -qstdlogmsg -qprint yourmom.cpp

I simply get "Compilation failed." (Shouldn't I be getting compiler
messages to the screen with "-qstdlogmsg"?)

In any case, the helpful joblog says:
SUGGESTION: Try using "-qlanglvl=rightanglebracket". It looks like you are
trying to use the associated C++0x
feature.


So, I try
ixlc -+ -oBEAK/XXX -qlanglvl=extended0x -qstdlogmsg -qprint
-qlanglvl=rightanglebracket yourmom.cpp

then get
INVALID COMPILING OPTIONS:-qlanglvl=rightanglebracket

:-(

v.push_back(111);

string s = c;
cout << s << endl;
cout << "i=" << i << endl;

cout << "i + x=" << i + x << endl;
for (int i : v) {
