[Bug c/19438] New: Unable to build cross-gcc to target powerpc-eabi

[qty154 at yahoo dot com]

I downloaded and installed cygwin, version of cygwin1.dll is 1.5.12-1.
I downloaded gcc-3.4.3 sources, gcc-3.4.3.tar.gz, and unpacked it to 
/home/gcc-3.4.3
Then I wanted to build a gcc cross-compiler for target powerpc-eabi (mpc5xx)
I used this to configure:
@ /home/gcc-3.4.3: mkdir obj
@ /home/gcc-3.4.3: cd obj
@ /home/gcc-3.4.3/obj: ../configure --prefix=/usr/local --with-gnu-as --with-gn
u-ld --disable-threads --with-cpu=powerpc --enable-languages=c,c++ --target=pow
erpc-ppc-eabi
I even tried this:
@ /home/gcc-3.4.3/obj: ../configure --prefix=/usr/local --with-gnu-as --with-gn
u-ld --disable-threads --with-cpu=powerpc --enable-languages=c,c++ --target=pow
erpc-eabi

and I issued make:

@ /home/gcc-3.4.3/obj: make

Then I got this error message (in both configure cases)

...

which as gives the following: /usr/bin/as
as --version gives the following:

At this point the cross-compiler itself is built.  You need a cross-assembler to
proceed, i.e you need to have an 'as' with --target=powerpc-eabi and properly
declare it when configuring the cross-compiler.  See the docs.
