hmmm, maybe there's something to look into here.
unless you've arranged to use something different (e.g. icc),
the compiler is still gcc/g++...  thus it "feels" like something
may be recording the compiler usage too early in the process,
or without enough sophisitcation...

what is it that determines that "the compiler used to build Qt is
different from the compiler used to build a particular Qt plugin" ??
