[ROOT] problem with rootcint and array initialization

Hi,

root cvs, linux, gcc3.2. This is the relevant part of the header:

#ifndef INCLUDE_TRIGINFO
#define INCLUDE_TRIGINFO
namespace tI {
    const int nTrigs=5;
    const int nHists=2<<(nTrigs-1);
    const char* trigNames[nTrigs]={"MU_2TRK3_L2M0",
                                   "2MU_A_L2ETAPHI", "2MU_C_2L2_2TRK",
                                   "2MU_A_L2M0",
                                   "MUW_L2M0_2TK3_MM"};

    TH1F* fHAll[nHists];
    TH1F* fHYes[nHists];
    TH1F* fHEff[nHists];
...

This happens when compiling my source:
g++ -c zbb_tmb_tree/TMBTree_bu_2MU_trigeff.C `root-config --cflags` -I. 
-Ikinem_util -Itmb_tree -Itmb_bcjet -Imc_analyze && echo Happy
Happy

And this happens when building the dicts for a class which includes this 
header:

Works fine without the namespace. Am I doing something wrong here, or is 
this a problem with rootcint?

Axel.
