[cfe-dev] clang cannot parse libc++ headers? <vector>

Hi,
I was trying clang on windows. I just compiled the latest version from
svn (updated llvm also).
compiling a simple C program works great but I could not compile any C++
one.
The msvc headers don't parse, the gcc4.4 either (vararg template) and I
don't have an older version of mingw. So I decided to try llvm libc++
but juste including <vector> give this (compiled with clang -std=c++0x
test.cpp):
In file included from test.cpp:3:
In file included from C:\perso\libc++\include/vector:242:
C:\perso\libc++\include/__config(119) : error: 'char16_t' cannot be
signed or unsigned
typedef unsigned short char16_t;
^
C:\perso\libc++\include/__config(119) : error: 'short char16_t' is invalid
typedef unsigned short char16_t;
^
C:\perso\libc++\include/__config(120) : error: cannot combine with
previous 'int' declaration
specifier
typedef unsigned int char32_t;
^
I "fixed" these error by modifying __config, but clang should be
detected... but the problem is next:
In file included from test.cpp:3:
In file included from C:\perso\libc++\include/vector:243:
In file included from C:\perso\libc++\include/__bit_reference:15:
In file included from C:\perso\libc++\include/algorithm:554:
C:\perso\libc++\include/memory(3317) : error: expected the class name
after '~' to name a
destructor

^
and finaly a crash:

definition", file C:\perso\ll

clang++: error: clang frontend command failed due to signal 2147483645
(use -v to see invocation)
Is this expected to work? I was thinking that libc++ was compiling with
clang. Did I dream or is it a regression?
regards,
Cédric
