I have a problem when I want to compil with a compiler other than g++

I explain me :
- I want to compil an exemple from qt-x11-opensource-src-4.3.1
- ./qt-x11-opensource-src-4.3.1/examples/dialogs/standarddialogs
- I do the qmake ...
- then, Makefile

Qt Code: 
  1. g++ -c -m64 -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I./qt-x11-opensource-src-4.3.1/include/QtCore -I./qt-x11-opensource-src-4.3.1/include/QtGui -I./qt-x11-opensource-src-4.3.1/include -I. -o dialog.o dialog.cpp
To copy to clipboard, switch view to plain text mode 

The issue is ok

If I use the ibm's compiler xlC to power architecture :

Qt Code: 
  1. xlC -c -q64 -O2 -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I./qt-x11-opensource-src-4.3.1/include/QtCore -I./qt-x11-opensource-src-4.3.1/include/QtGui -I./qt-x11-opensource-src-4.3.1/include -I. -o dialog.o dialog.cpp

What do you think of these errors ??

Usually, I haven't got any problems with this compiler (qt3, X11, ...)
