Comment(by easieste@…):

 Apparently related to #30012

 It looks like this error occurs when one has Xcode 4 installed on OS X
 10.6, as the configure process on my machine picks up the llvm-gcc-4.2
 compiler.

 Patching as follows enables the build to get past the hipe error on OS X
 10.6:

 The "correct" thing is probably to first detect if XCode 4 is installed on
 OS X 10.6, then change the compiler flags.  Can someone reference an
 example of such logic somewhere?

 Or should we just force the use of gcc-4.2 under OS X 10.6?
