This is a release build (-O2). So the decrease in size is small, but measurable. I haven't tested the executable sizes on Windows yet. Strangely, on Windows, this change has almost zero effect on build time. The time to run qmake has increased slightly (about 3:10 to 3:20) but the remaining build time (everything within jom.exe) only dropped by about 8 seconds (total of about 7 minutes). On Macintosh, the qmake time also increases slightly but the rest of the build is about 45 seconds faster (6:15 to 5:29). The Windows builds are release builds with VS2017. Adam
