Does this means that that change finally solved the problem?

If so, i commited a hopefully multiplatform-save change to set the 'default' 
tool to mingw just when sys.platform=='win32'. (rev 11361 for libs and 11363 
for apps and plugins)

If this works, it might make the CCFLAGS='' parameter useless. So, once it is 
working, try to remove it and see what happens.

The next step will be building the applications. Although your project is 
centered on Annotator i recommend to build first the NetworkEditor. Being 
simpler it will highlight faster any problem we could have.

To do so, use the scons lines at the end of the crosscompilation wiki:

but removing the 'crossmingw=1' option and pointing QTDIR and MINGWSANDBOX to 
the proper path. 

Did you installed Qt4 for windows? You will need it:

Qt version 4.4 has just been released but no mingw binaries yet :-( Anyway we 
didn't tried the new Qt release even on linux and that would be too many 
experiments at once. ;-)
