gcce compiler output: many false error messages

When compiling a simple Qt for Symbian app with abld/gcce, the build tool chain returns a lot of output.
QtCreator seems to see to many errors in the tool chain output. Actually, with a successful build, there are 7 false error in the build issues.

CompilerOutput.txt contains the output in Creator separated by colors.

Note #1: The whole output (CompilerOutput.txt) does not contain the word "error".
Note #2: That as compiler version, I used gcc version 4.3.3 (Sourcery G++ Lite 2009q1-162)
