TQString::vsprintf

I tried compiling tde-suite-r14.0.1 from the source code online and tqt3-r14.0.1 is missing a call declaration called TQString::vsprintf that is needed to compile tdenetwork-r14.0.1. The function TQString::vsprintf is found in tqt3-r14.1.0, but when I compile it, and upgrade my system to tqt3-r14.1.0, the desktop still works but it changes the entire look of my applications to a very look, similar to an lod gtk look. I checked both tqt3, and tdenetwork commits to see if / or when TQString::vsprintf was added to the r14.0.1 build or if TQString::vsprintf was known by some other name, in a previous commit of tdenetwork ... Anyway to get to the point comparing tqt3-r14.1.0 and tqt3-14.0.1 the file src/tools/qstring.cpp r14.01 is missing the function TQString::vsprintf. so would it be safe to just copy it from the tqt3-14.1.0/src/tools/qstring.cpp to the tqt3-14.0.1/src/tools/qstring.cpp... what would be the best way to fix the problem, so tdenetwork-r14.0.1 will successfully build, and my desktop will not lose it's Trinity desktop look, to an almost generic gtk desktop look. Currently tqt3-r14.1.0 is the only r14.1.0 package, and all the others are r14.0.1 packages, and by using tqt3-r14.1.0 tdenetwork-r14.0.1 successfully compiled.
