The other got ya with qt5 is windres.exe.
It uses MS's popen, which calls cmd.exe and thus introduces a 8k limit.
This would mean qtdeclarative wouldn't build for me.
My solution was to change windres.exe to use a custom popen on Windows, 
one that calls CreateProcess with the command line directly, accessing 
the higher 32k limit.

Anyway, really pleased there is progress on this. :-)
