[Interest] Can't compile Qt 5.0 RC with Mingw,

[Bruno Cabral]

Looks like qtbase\src\corelib\io\qprocess.cpp is using a deprecated version
of swprintf.

On line 85 it should read swprintf(pipeName,256, L"\\\\.\\pipe\\qt-%X",
qrand());

This is the standard and is followed by GCC and Visual Studio. The older
without the size was a hack on VS.

Can someone submit this ? I can't afford the work of needed to submit a
patch.

Thanks,
Bruno Cabral

At first glance, this looks very wrong. I've also been noticing a lot of
conversions from size_t to int which will result in data loss on some
systems. Should be uint32 instead of int.
