Created attachment 22494

gcc46-pr33637.patch

I guess the important question is, do we support (or even just pretend to
support) configuring gcc (or binutils and other tools) in paths with
spaces/tabs in pathnames?

If not (it would surprise me if everything worked, e.g.
$1=`cd $with_build_time_tools && pwd`/$2
in acx.m4 will not do what it expects if with_build_time_tools contains spaces
in it), then I'd say this patch is the way to go.

Otherwise, either we just shouldn't concatenate the extra arguments into
NM_FOR_TARGET/AS_FOR_TARGET, but substitute into different vars and use them
that way, or just special case trailing " -X32_64" and " -B -X32_64" in this
script.

I agree.  We might even warn about it in the toplevel.

Actually, the gcc/configure.ac hunks are needed too (just tested on
x86_64-linux
with a hack which added the (ignored) -X32_64 to extra_nmflags_for_target in
toplevel configure{,.ac}).
Which in the end means that the

http://overlays.gentoo.org/proj/alt/export/51702/trunk/prefix-overlay/sys-devel/gcc/files/4.3.0/targettools-checks.patch

patch is correct and should be applied.

Michael, can you please write a ChangeLog entry for it and mail to
gcc-patches@gcc.gnu.org ?
