[Development] Build issue with configure -developer-build for qtbase?

[Carl Schumann]

An update ...

This build error was on our production 32 bit systems.   We are just 
know in the process of transitioning to 64 bit systems.  (We have a lot 
of legacy and limited downtime opportunities to make big changes.  We 
are also a little short on staff.)

I extracted this build issue into a simple test file, main.cpp, which is 
attached.   I then tried to reproduce the build error on on both 
systems.  These results are also attached.   Bottom line the build issue 
is present only on 32 bit system.

I am guessing you all have transitioned to 64 bits for your build 
system, etc.   What is your policy statement on 32 bit systems?   Try 
not break them?  They deserve to get broken? ???   For me I will 
probably just transition my work to 64 bits even if our legacy stays 32 
bits for a while longer.

Sincerely,
Carl
