I'm using gentoo distribution (including gmp/mpfr/mpc) that could compile
gcc-4.5.0, 4.5.1, and many snapshots correctly, including the recent one
gcc-4.5-20100902,
but when I tried to compile gcc-4.6, any snapshot version, even recent
gcc-4.6-20100904,
it always failed, the recent one failure compiling is:

I don't know what happened with that? When I search the
'ggc_alloc_cleared_lang_type' macro,
it really doesn't exist in the gcc-4.6-20100904 source, nor under /usr/include,
so what is
that macro real dependency?

This seems to be defined in a header generated during the build
into the $BUILD/gcc :
[r...@localhost gcc]# grep ggc_alloc_cleared_lang_type *.h
gtype-desc.h:#define ggc_alloc_cleared_lang_type_u() ((union lang_type_u
*)(ggc_internal_cleared_alloc_stat (sizeof (union lang_type_u)
MEM_STAT_INFO)))
On CentOS 5.5/ia32 the build seemed to succeed for the
'x86_64-linux-gnu' target, using gcc-4.1.2 as the host
and build compiler. Must check the Fedora 13/x86_64
host with its gcc-4.4.4 too but I wouldn't expect any
change with it...
So maybe the Gentoo distro has some problem...
