Qt fails to compile on Aix 5.3 64-bit using XL C 10.1

Hello,

I faced a problem compiling Qt from the sources on an Aix 5.3 64-bit using IBM XL C 10.1.

$ uname -a
AIX newton 3 5 00006E42D900

./configure -platform aix-xlc-64 -prefix
/usr/local/tools/64bits/qt/4.5.2/dynamic -no-separate-debug-info
-no-openssl -no-largefile -release -no-qt3support -shared -no-svg
-no-webkit -no-nis -no-cups -no-dbus -no-opengl -no-sm -no-xinerama
-no-xcursor -no-xfixes -no-xrandr -no-xrender -no-fontconfig
-no-xinput -no-xkb -no-glib -no-phonon -no-phonon-backend -no-gtkstyle
-qt-zlib -fast -no-rpath -nomake examples -nomake demos -nomake doc

The attached patch solves it.

Feel free to ask for more information or testing!
