Appears to be 2 types of errors 

• Errors due to class changes going from Qt3 to Qt4 – These could probably be addressed with correct switch to include q3support library that is included with Qt4.  I copied the q3textstream.h to the working directory to get around referencing error.  By not setting this I am forcing all the references not compatible with Qt4 to surface.
• Errors due to the translation files not being available for access

Migration Qt3 to Qt4: They changed the name of class members that APPEAR to do the same thing.  

• homeDirPath becomes: homePath
• setName becomes setFileName
• QString::stripWhiteSpace() becomes QString::Trimmed()
• QLocale class may have to be used to replace QTextCodec::locale  … see QLocale::languageToString
• char QChar::latin1 () const  Use toLatin1() instead.
• QApplication::setMainWidget   goes away?

• Qt3toQt4 tool
• QT += qt3support, to my projects.pro file  – this cleared the errors due to missing class members.  The remaining errors were those of missing PACKAGE_VERSION, LANGUAGEDIR, BITMAPDIR
