Hi, all,
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? the prerequisites page seems not help me,
http://gcc.gnu.org/install/prerequisites.html
Who have successfully build gcc-4.6 please help me, or have any clue, I have
searched that ggc_alloc_cleared_lang_type
through google, but didn't find out any meaningful results,
please make sure have my email address on cc-list that I can receive your
email, because I didn't subscribe such
high volume mailing list,
Thank you very much,

hm... an obvious question would be if you have your toolchain correct?
(but you probably do..(I used this to build
4.6.0..:http://cross-lfs.org/view/svn/x86_64-64/))
in your case I see something with lang... maybe your CFLAGS are set
wrong to the wrong machine?! over here my CFLAGS look like this:
CFLAGS="-m64 -mtune=core2 -march=core2 -O2 -pipe -fomit-frame-pointer
-fstack-protector -w" CXXFLAGS="${CFLAGS}" MAKEOPTS="{-j3}"
keep in mind this is for a intel iMac... your system could be diff..
