xlC V9 problem compiling Qt 3.3.8

Hi,

has anybody tried compiling Qt 3.3.8 with the xlC V9 compiler? I've previously been able to use the xlC V5 and V6 compiler to build Qt 3.3.8 with no problem. With the new V9 compiler, I get:

"../include/qmap.h", line 805.23: 1540-0253 (S) This use of undefined class "QVariant" is not valid.
"../include/qmap.h", line 805.23: 1540-1205 (I) The error occurred while converting to parameter 1 of "Param::Param(const QVariant &, QSql::ParameterType)".
"../include/qmap.h", line 797.23: 1540-0700 (I) The previous message was produced while processing "QMap<QString,Param>::operator[](const QString &)".
"sql/qsqlquery.cpp", line 1008.6: 1540-0700 (I) The previous message was produced while processing "QSqlQuery::exec()".
