REVISION SUMMARY
  In Qt 4, the compiler detection macros have no value, so they can't be compared
  against. So just use the compiler-specific ones.
  It also makes use of the fact that undefined tokens evaluate to 0 in
  comparisons.

TEST PLAN
  jriddell built it with GCC 5 and 7 against Qt 4 and 5.

REPOSITORY
  R31 Breeze

BRANCH
  master
