3.0.4 cross build fails on i686-pc-cygwin.

["Mack Lobell" <macklobell at hotmail dot com>]

Hi,

i'm trying to build a 3.0.4 cross compiler for powerpc target. Binutils is 
installed in /usr/local/powerpc and compiled for powerpc-eabi.

The build was configured the following way:
$ gcc --version
2.95.3-5
$ target=powerpc-eabi
$ host=i686-pc-cygwin
$ build=i686-pc-cygwin
$ prefix=/usr/local/powerpc
$../../gcc-3.0.4/configure --enable-languages=c,c++ --with-included-gettext 
--enable-shared --enable-threads --target=$target --with-newlib 
--prefix=$prefix --with-ld=/usr/local/powerpc/bin/powerpc-eabi-ld.exe 
--with-as=/usr/local/powerpc/bin/powerpc-eabi-as.exe --host=$host 
--build=$build -v > cross_conf.log 2>&1
$ make CFLAGS="-v -save-temps" > cross_make.log 2>&1

The build fails when trying to compile libiberty/argv.c.

If needed i have the logs from make and configure, and i have the 
preprocessed files.

I have the same problem trying to build a 3.0.3 cross. Is this is bug or is 
it me?

Regards.
