Vector <TH1F*> compilation problem with clang on MacOS 10.7


I am trying to make a vector of TH1F* inside cint:

root [0] std::vector<TH1F > toto
Error: Symbol vector<TH1F
>toto is not defined in current scope (tmpfile):1:
now if I do
root [1] #include< vector >
root [2] std::vector<TH1F *> toto
I have this error

if __has_warning("-Wreturn-type-c-linkage")


Do you know what I am doing wrong ? by advance thank you
(sorry if the question was already asked)
I am using root 5.34/00 under mac os x 10.7


please update XCode to the newest one supported on 10.7 and this problem should go away.

Cheers, Axel.
