The alternative would be to use Clang ?, but this does not seem to work for the python wrapping part (http://itk-insight-users.2283740.n2.nabble.com/Re-How-to-get-ITK4-and-Python-wrapping-to-work-on-Mac-OSX-10-7-td7581624.html, http://www.itk.org/Wiki/ITK/WrapITK_Status).

I know we have to wait that the gccxml formula is added back to homebrew, I made this PR so that people needing ITK could test everything before the merge in master.

Perhaps I should ask the guys at gccxml why their last tag on git is 0.6.1, and the version which is installed is 0.9 ? They could perhaps tag it to 0.9 so that we would have a stable gccxml version ? What do you think ?
