[Development] tools/configure with mingw build error

[Peter Kümmel]

I've tried to build qtbase
1. on Windows 7
2. rubenvb's mingw-w64: 
http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/rubenvb/gcc-4.7-release/
3. in Windows shell cmd.exe
4. as shadow build with ..\qtbase\configure.bat -fast -nomake demos -nomake examples -release

It copies the headers and starts to build configure.exe but after compiling three files
it starts to links and complains about missing .o files.

Have I missed something or is building with mingw in cmd.exe not supported?
(looks like tools/configure/Makefile.mingw is for sh)
