[Qt-interest] QSharedMemory::create takes an int... why?

[Thomas Dähling]

Sorry for the double post, but this made me google around a bit, and
after it appears that the size of int is depending upon the compiler
you use. So, to get it to use more than 4 GB you'll have to find a
compiler that takes int as 64 bit.
