building with cegcc

[Maurice Kalinowski]

Hi,

to summarize your issues, we do not support neither cygwin nor MinGW for 
Windows CE at the moment. The only supported build toolchain is by using 
the Microsoft crosscompilers included in the Microsoft Visual Studio 
2005 and following.

We cannot tell you if that is going to change in the future, but for now 
there is no official supported way in using any of these compilers with 
the Qt/WinCE package.


Best Regards,

Maurice Kalinowski
