Building cross-compiler w/ linux host and mingw target.

[Lars Andersen <lars at rimfaxe dot com>]

I'm trying to build a cross compiler with :

host=i686-pc-linux-gnu
target=i686-pc-mingw32
prefix=/usr/local/cross_gcc/mingw

I'll describe what i do, and if someone can see where i go wrong it'll
be great. Or even better, if anyone has made it work, please post what
packages was used and how they were configured. 

I unpack the mingw 2.1 runtime and w32api 1.5 into
/usr/local/cross_gcc/mingw/i686-pc-mingw32
to get header files etc in place.

Then I install binutils 2.12 with the following :

> ./configure --target=i686-pc-mingw32
--prefix=/usr/local/cross_gcc/mingw 

> make
> make install

Set the path so i686-pc-mingw32-ar can be found :

> PATH=/usr/local/cross_gcc/mingw/bin:$PATH

Next up is gcc :

> ../gcc/configure --with-gnu-as --with-gnu-ld
--with-as=/usr/local/cross_gcc/mingw/i686-pc-mingw32/bin/as 
--with-ld=/usr/local/cross_gcc/mingw/i686-pc-mingw32/bin/ld 
--target=i686-pc-mingw32 --enable-threads=win32 --enable-java-gc=boehm
--enable-fast-character --prefix=/usr/local/cross_gcc/mingw
--disable-hash-synchronization --disable-interpreter
--enable-sjlj-exceptions --disable-shared --enable-libgcj

> make


Make fails, here is the last lines :
