VIVE L’AMOUR!
see these threads, for example:
[url]Make qtcint dies in v5.28.00.patches
[url]V5.28.00.patches with Qt backend dies in font / fontconfig
Some bug fixes related to Qt4 have been introduced into the “v5.28.00.patches” svn source code (and into the svn “head”), but NOT into older releases (as far as I know, of course). 
Note that there are still severe problems, awaiting Valeri to fix them. 
BTW. The “configure” options that you show were for “Qt3 configuration itself”, NOT for “ROOT using Qt3”. I doubt you are trying to configure and compile your Qt4 yourself, do you? I take whatever the operating system provides. For ROOT, I simply use “–enable-qt --enable-qtgsi”. 
A pitiful case, am I not?
