--- Comment #6 from Iain Sandoe <iains at gcc dot gnu.org> ---
JFTR, I had cause to use this today on powerpc-darwin9, and it seemed to DT=
RT -
so it would be useful to establish what it was that did not work before, th=
at
was fixed by the patch.

/src-local/gcc-git-11/configure
--prefix=3D/opt/iains/powerpc-apple-darwin9/gcc-11-3Dr2d
--build=3Dpowerpc-apple-darwin9 --enable-languages=3Dall --with-tune-cpu=3D=
G5
--enable-libphobos --with-libphobos-druntime-only CC=3Dpowerpc-apple-darwin=
-gcc
CXX=3Dpowerpc-apple-darwin-g++
--with-build-time-tools=3D/opt/iains/powerpc-apple-darwin9/gcc-11-3Dr2d/bin

Without the
"--with-build-time-tools=3D/opt/iains/powerpc-apple-darwin9/gcc-11-3Dr2d/bi=
n" the
system linker and assembler are found and used (which fails to work with D,
causing a bootstrap fail) with the option, the relevant tools are found and
bootstrap succeeded....

(so I am not sure what the original problem was
since $build is not specified in the summary, I guess we must assume it was
i686-pc-cygwin so perhaps the problem is specific to that setup?)=
