RE: Build problems; Please help

   Some More Updates on Build Problem. The assembler error was being
generated
because the -mthumb option to gcc was not being passed down to the
assembler.
Because the specs file didn't have that specified. So I added the line

%{mthumb:-mthumb}

to the asm specs in the file /home/jbrahma/local/zip/build-egcs/gcc/specs

The diff is

But I don't know how the specs file is generated from the source files.
So If somebody know where to put the patch in the sources, please mail
me. May be this patch should be also applied to the CVS. 

Thanks
