help needed for builing gcc tool-chain

["Prashant Batra (prbatra)" <prbatra@xxxxxxxxx>]

Hi All,

I am trying to build a 32 bit gcc/g++  tool-chain on a x86_64 bit Intel machine with, Red Hat Linux Enterprise -5 (2.6.18 kernel).

Gcc version of my machine is - 
gcc -v
Using built-in specs.
Target: x86_64-redhat-linux
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-libgcj-multifile --enable-languages=c,c++,objc,obj-c++,java,fortran,ada --enable-java-awt=gtk --disable-dssi --enable-plugin --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --with-cpu=generic --host=x86_64-redhat-linux
Thread model: posix
gcc version 4.1.2 20080704 (Red Hat 4.1.2-48)

I tried with the procedure mentioned on gnu wiki,  also mentioned in LFS. But none of the attempts was successful.

I  have some basic questions here : 

Changing the prefix to some custom location  other than /usr/src should make all the tools installed in the custom location?

I want to run the tool chain on this machine only, so my host and build systems are same, and I can omit them while configuring all my tools (binutils, gcc, glibc).
Is this correct?

The target of all these tools while configuring should be i486-gnu-linux or I can omit this so that the gcc/g++ gets  compiled for x86_64 and when I need a 32 bit executable,
I can use -m32 switch while compiling? Will 32 bit static and shared libraries be available in this case?

I want static libraries for both gcc and stdc++, is there any special flag that I should give/or not give to build these static libraries?

Can someone please point me in right directions, as I am doing this for the first time? Any links to the steps will be really helpful.

Regards,
Prashant
