C++ porting : No such file or directory

[Sivaprasad.pv]

Hi Kai Ruottu,
     Thanks for your suggestion.As you have suggested i have followed 
the order for building.But Amongst the 3 steps  I have  completed the  
first 2 steps. now  i want to build libraries like libstdc++ .I have 
gone through the  libstdc++-v3  porting document from url 
"gcc.gnu.org/onlinedocs/porting".From that  I think, I have to add  
atomicity.h file for our target(proprietary processor).but i want to 
know in detail about  atomicity.h file  so can you please suggest me any 
document which will help me to porting libstdc++.

   
 some specific information :
      host : X86 with fedora core6 operating system
      target: proprietary processor without any os

 configuration options used for building c++ compiler :

     $SRC/gcc-3.3/configure --prefix=$RELDIR --target=$TARGET 
--enable-languages=c++  --with-newlib --with-gnu-as --with-gnu-ld   
--host=i686-pc-linux-gnu  --enable-sjlj-exceptions --with-dwarf2
          make all-gcc
          make install-gcc

 configuration options used for building newlib:

   $SRC/newlib-1.11.0/configure --prefix=$RELDIR --target=$TARGET 
--host=i686-pc-linux-gnu
         make all install

  I am quiet new to building gnu tools.I am in a stage of learning 
basics  of building and using gnu tools. if I give any contradictory 
options please excuse me and suggest  the correct procedure.
