hi all, i've been trying to compile some universal binaries (i32/x86_64) of qt 5.2. while i've been able to generate some libraries, mainly my disabling precompiled headers and compiling without sse3/4/avx support, i wonder: are UBs expected to work or will i run into some troubles? (e.g. are the headers/mocs architecture-independenct)? thanks a lot, tim
