This appears to be an issue with Xcode 4.4, not MacVim. A solution to your problem is posted at:

Nope. Does not help if you read further comments.

I debugged an issue with the same symptoms a while ago. It happened when I ran `make` (which builds vim) with a different compiler than xcodebuild (which builds MacVim). Maybe 4.4 uses clang by default for the MacVim build -- in that case, run `CC=clang ./configure; make -j6` to build the corresponding vim binary. Make sure both vim and MacVim are built with the same compiler.

That did the trick. Thank you!

Yes, "CC=clang ./configure; make -j6" works. But *jeez* it is annoying
that special steps have to be taken.

Plus, during the compliation of the Vim binary, all sorts of warnings
are thrown out that weren't there before. And it's annoying because I
usually want to just run the ./configuring part first. In which case, I
can do "export CC=clang" and then the configuring on a separate line,
but then I have to remember to get rid of $CC after building MacVim lest
I accidentally botch building something else.

And now my steps for building have to be different between 10.7 and up,
and 10.6 and below.

Arrgh! Apple!

Hey, has anyone else noticed that there is no need for this maneuver at all on Mountain Lion, even though it has XCode 4.4 as well? I know there's a different package of command-line tools for 10.8 than for 10.7; maybe that's the difference.

Maybe a way to fix this would be to change the XCode project to use a
specific version of GCC rather than just the 'default compiler'. Then
autotools and Xcode will use the same one, right, because autotools will
pick up GCC first? I'm sure it's still not foolproof, but perhaps it's
better?
