Error compiling GCC 4.3.1 on Solaris 10 x86 (Update 5)

Question

I am getting error when building GCC 4.3.1 on Solaris 10 x86.
Have any of you built GCC 4.3.1 on Sol 10 x86?
Here's the background:

How do I build GCC 4.3.1 on Solaris x86?
Thanks

Answer 1

The bootstrap compiler is GCC 3.4.3.
I tried Sun's assembler (/usr/ccs/bin/as) too and got another error (below)
I also tried bootstrapping with Sun's Studio 12 compiler but that too failed.
