Bug#29953: Problems compiling KDevelop 2.0 with GCC 3 on Alpha

[Norman Jordan]

Changing line 77 of kdevelop/dbg/breakpointdialog.cpp to
  label2->setMaximumWidth(QMAX(label1->sizeHint().width(),
allowed that file to compile on Linux Alpha, however KDevelop still fails to compile with the following error:

g++-3.0 -DHAVE_CONFIG_H -I. -I. -I../.. -I/usr/include/kde
-I/usr/include/qt -I/usr/X11R6/include -DNDEBUG -O2 -mieee -fno-exceptions
