Cannot build on Fedora: wrong CPUTYPE?

[Dubhead]

make fails like this:

compile: rt/i686-unknown-linux-gnu/sync/timer.o
In file included from /usr/include/features.h:387:0,
                 from /usr/include/stdlib.h:25,
                 from ../src/rt/sync/../globals.h:11,
                 from ../src/rt/sync/timer.cpp:1:
/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory
compilation terminated.
make: *** [rt/i686-unknown-linux-gnu/sync/timer.o] Error 1

The host is Fedora 16 x86_64; there is /usr/include/gnu/stubs-64.h but not stubs-32.h.
The last part of configure's output is:

configure: writing configuration
configure: 
configure: CFG_SRC_DIR          := ../
configure: CFG_BUILD_DIR        := /home/miura/Rust/build
configure: CFG_OSTYPE           := unknown-linux-gnu
configure: CFG_CPUTYPE          := i686
configure: CFG_CONFIGURE_ARGS   := 
configure: CFG_HOST_TRIPLE      := i686-unknown-linux-gnu
configure: CFG_TARGET_TRIPLES   := i686-unknown-linux-gnu
configure: CFG_C_COMPILER       := gcc
configure: CFG_PREFIX           := /usr/local
configure: CFG_LLVM_ROOT        := 
configure: CFG_LLVM_SRC_DIR     := ../src/llvm
configure: CFG_LLVM_BUILD_DIR_i686_unknown_linux_gnu := /home/miura/Rust/build/llvm/i686-un ...
configure: CFG_LLVM_INST_DIR_i686_unknown_linux_gnu := /home/miura/Rust/build/llvm/i686-un ...
configure: 
configure: cp ../Makefile.in ./Makefile
configure: 
configure: complete
configure: 

So it looks like configure wrongly detects the CPUTYPE as i686.

configure is not wrong exactly, it's just that x86_64 support is not quite there yet. Should be coming into master very early next week.

I see. I'll close this issue for now. Thanks nikomatsakis.
