else with this issue, here is a short bash script that you can put in
your cloned repository root and run it before doing ./configure. You
only have to run it once per pull. The script merely comments out the
"offending" lines, though one could also replace 4.2 with "", or leave a
totally blank line, or destroy the whole line.
sed -i -e "s/\(GCC_VERSION = 4.2\;\)/\/\* \1 \*\//" src/MacVim/MacVim.xcodeproj/project.pbxproj
sed -i -e "s/\(GCC_VERSION = 4.2\;\)/\/\* \1 \*\//" src/MacVim/PSMTabBarControl/PSMTabBarControl.xcodeproj/project.pbxproj
