Upstream-Status: Inappropriate [no development on qt4 now]
RP 2016/5/26

Index: qt-everywhere-opensource-src-4.8.7/configure
===================================================================

Amend this and change the logic to assume all compilers are suitable
exept 3.3x resp. 3.2x and older ones.
