[Development] Qt4.8.2 link error with MinGW-builds GCC 4.7.1 on Windows 7

[andy fillebrown]

Hi Yang,

I've had similar issues in the past.  After a lot of head scratching I
discovered the error was due to a very long command line in the
QtWebKit make file.  The only way I could figure out to work around
the problem was to move the Qt source tree closer to the root
directory of the hard drive so the file name lengths were short enough
to avoid the errors.

I created a one letter folder at the root of the drive (C:\-\), then
put the Qt source code there.  In my experience, you can get about
10-12 characters total in the directory name, including backslashes.
Any more than that and the web kit build starts failing again.

Hope that helps.

Cheers,
~ andy.f
