[Interest] Qt 5.6.0 problems

[Tony Rietwyk]

Hi Everybody, 

Using qt-enterprise-windows-x86-msvc2013-5.6.0.exe package coming from
5.5.1: 

1) The qmake rule:

win32 {
	# These aren't available in some Windows versions so delay loading
them until we can check they are available
	LIBS += /DELAYLOAD:mfplat.dll
	LIBS += /DELAYLOAD:mfreadwrite.dll
}

in the resulting VS 2013 project now gets a linker error  "cannot open input
file '\DELAYLOAD:mfplat.dll'"  so it seems qmake is replacing the slash with
backslash.  Is there a way that I can prevent that happening? 


2) A new header file gives warnings in VS 2013 for EACH file that is
compiled: 

1>C:\qt\Qt5.6.0\5.6\msvc2013\include\QtGui/qrgba64.h(100): warning C4242:

This makes finding compilation errors painful.  Would modifying the header
to add some static_casts cause problems in our binaries not matching the
pre-built DLLs?  

3) Some of the Qt sources do not match when debugging and stepping into
those routines.  Should I raise a bug for these?  Is this possibly due to
inconsistent line endings?  Are they cleaned for each target as part of the
package build process?
