This just occured to me when I was about to commit the i386/crtprec
patch.  Testing for that one has completed successfully, but even if I
commit that one, the crtfastmath one is still pending.

I've just submitted the revised version, asking for approval so I can
commit both i386/crtprec and crtfastmath to gether to get us out of this
mess.

Sorry.

I configured the build with

../work/configure --prefix=/opt/gcc/gcc4.7w
--enable-languages=c,c++,fortran,objc,obj-c++,java,lto --with-gmp=/opt/sw64
--with-libiconv-prefix=/opt/sw64 --with-system-zlib --with-cloog=/opt/sw64
--enable-cloog-backend=isl --enable-lto

A nonparallel make gives

# multilibs.

This has nothing to do with the problem at hand.  It's from
libgcc/config/t-slibgcc-darwin (install-darwin-libgcc-stubs) where the
symlinks are created unconditionally, irrespective of target.

With the patch in http://gcc.gnu.org/ml/gcc-patches/2011-07/msg01068.html,
bootstrap fails with:

make[5]: *** No rule to make target
`../../../../work/libgcc/config/i386/crtfastmath.c', needed by `crtfastmath.o'.
 Stop.

at stage1 for -m32.

Apparently something went wrong in the patching process, trying revision
176241.

You could probably say so: those are git-style patches containing
renames, and only git GNU patch can handle those, otherwise you have to
perform them manually.

That said, please update to rev 176242 instead.  Unless I made a
mistake, that one should bootstrap again.

Sorry for the mess.

Great.  Please close the PR one bootstrap finished.

Thanks.
