 gccxml_builtins.h can be copied from 4.6 to 4.7 as a starting point. The other headers were all created by first committing original headers from the corresponding version and then committing fixups to help gccxml's parser handle things.

Unfortunately this is getting harder with every new GCC because gccxml still uses a GCC 4.2 parser internally and the GCC system headers are using more and more new parser/language features.

 I see no mention of GCC 4.7 being released at gcc.gnu.org, nor a branch in their repository:

 Yeah, it's still a bit ahead. I think that the source for 4.7 is in trunk, according to their timeline, they'll cut a 4.7 branch in March.

 Great. I'll need two patches for gccxml. The first should add the *original* versions of these files from GCC 4.7:

 bits/stl_algo.h
 bits/stl_algobase.h
 complex
 emmintrin.h
 iomanip
 mmintrin.h
 xmmintrin.h

to GCC_XML/Support/GCC/4.7 (and perhaps new ones that we'll need to patch for 4.7). The second patch should apply changes to those files to fix them up for gccxml's parser. Look at the equivalent changes made to 4.6's headers for examples.

 I have uploaded a tar file containing copies of the original files and a patch to adapt them to the gccxml parser.
