__has_trivial_destructor() returns false for all reference types, but
should return true according to documentation. The documented behavior
is consistent with what is required by the c++0x draft.
Environment:
System: Linux cranium 2.6.18-8.el5xen #1 SMP Fri Jan 26 14:29:35 EST 2007
x86_64 x86_64 x86_64 GNU/Linux
Architecture: x86_64
host: x86_64-unknown-linux-gnu
build: x86_64-unknown-linux-gnu
target: x86_64-unknown-linux-gnu
configured with: /build/sebor/src/gcc-4.3.0/configure

--with-gmp=/nfs/devco/contrib/linux/gmp-4.2
--with-mpfr=/nfs/devco/contrib/linux/mpfr-2.3.1
How-To-Repeat:
Attempt to compile the following code as g++ -std=gnu++0x t.cpp
typedef char assert_0 [__has_trivial_destructor (int&) ? 1 : -1];

Fix:
A workaround would be to use a wrapper template that has a special case
for reference types.
