Binary package hint: gccxml
gccxml fails to parse standard header stdio.h in Intrepid, whereas it works perfectly using the hardy package
steps to reproduce:
$> echo '#include <stdio.h>' > foo.h
$> gccxml foo.h

Confirming, __builtin_
In order to really support these we would have to update GCC-XML's
internal parser to be GCC 4.3. Since this has not yet been done we
get most of the way by defining some of these as macros with fake
answers. It is enough to get through GCC 4.3's C++98 standard
library.
As workaround, you can add this at the end of the file:
int __dummy__(...);
#define __builtin_
The example you give "compiles" fine, and some quite complex code does as well.
