__int128 and "unsigned __int128" are not fundamental types

[RomanYakovenko]

Hello.
I am using the following environment:
$ uname -a
Linux roman 4.10.0-30-generic #34-Ubuntu SMP Mon Jul 31 19:38:17 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
$ lsb_release -a Description: Ubuntu 17.04
Release: 17.04
Codename: zesty
$ castxml --version pyplusplus/hg/default
castxml version 0.1-gd5934bd

CastXML project maintained and supported by Kitware (kitware.com).

clang version 3.8.1-9ubuntu1 (tags/RELEASE_381/final)
Target: x86_64-pc-linux-gnu
Thread model: posix

The following code was compiled:
void abc(int i, ...);

castxml generated the following xml file:

<GCC_XML version="0.9.0" cvs_revision="1.139">

























</GCC_XML>

As you can see __int128 and 'unsigned __int128' are fundamental types, while __int128_t and __uint128_t are just typedefs for them.

I think this should be fixed in cpptypes, but may be I am wrong. Did not tested the output in other environments. May be the fix is more complex.

Regards,
Roman
