cross compiler - gcc compile failed

[remy harel]

   Hi list,

 I'm currently compiling gcc on a linux 2.6 box and
the first try was using gcc 3.4 to compile gcc 3.2
with specific flags ( -march -mtune -O3 etc... in fact
optimization flags for future tests ) and all went
well.

 I'm used to do it since I'm a gentoo user and a linux
well experienced user ( professionnal and home use ).

 But I want to set up a linux server to compile
binaries for linux ( so a native linux gcc compiler -
piece of cake ;) ) and also a toolchain to cross
compile c++ sources from linux host to win32 target. I
encounter some  troubles , the first step ( binutils
2.15) is ok :

./configure --prefix=/usr/local/cross-win32
--target=i386-mingw32msvc --with-gnu-as -with-gnu-ld
--disable-multilib -v --host=i686-pc-linux-gnu && make
&& make install

then I add /usr/local/cross-win32/bin to $PATH, 
cp -Rvf  mingw runtime/include to
/usr/local/cross-win32/i386-mingw32msvc

I unpack gcc sources, 

./configure --prefix=/usr/local/cross-win32
--target=i386-mingw32msvc --with-gnu-as -with-gnu-ld
--disable-multilib -v --host=i686-pc-linux-gnu 

Everything is ok with a such configure line, and it
even says that links are now ready to set up a cross
compiler from linux i586 to win32 i386.

  But then, the make step crashes, quite early. :

--------------------------------------------------

 I don't understand why it crashes, it's really weird.
Do the march mtune etc.. options are not compatible
with --target and --host or something like that ?

I use gcc 3.3.4 to compile gcc 3.3.2 as a cross
compiler. If someone could tell me what this is all
about please...Or a good updated cross compile how-to
( already read kegel, adams, etc... )

 Please answer to all because I didn't yet suscribed
to this gcc list ( I'm already on debian lists and
it's high volume enough )

Any feedback would be appreciated,
Regards,
