I'm not particularly focused on optimization, so I wouldn't be enabling lto. (I'm also not using Webkit.) > On the other hand, why rebuild what you already have?

My current "everyday" installation of Qt (and some other small libraries) was built with a tdm mingw32 gcc build: g++ --version: g++ (TDM-2 mingw32) 4.4.1 I just sort of assumed that I wouldn't be able to mix my current (tdm 4.4.1) Qt libraries with code compiled with the new compiler. Do I understand you correctly that they should be compatible? (By the way, my tdm gcc uses sjlj exceptions.) > ... > Ruben > ... Thanks. K.
