Error building gcc 4.2.1 for sparc target?

[mike]

Hi all,

My host: Linux Redhat. Host tools: gcc 4.1.1
Target : sparc-rtems

I followed the documentation to build binutils 2.17 without any problem.
When I tried to build gcc 4.2.1 (same errors for 4.1.1) for
'sparc-rtems' target following the doc,
I got the following errors during "make all". I would really appreciate
any pointers.
Thank you.
