Well, now that you have marked the thread as answered,
( that is what your post # 2 does )
... I will show you my notes from yesterday :
Are you building for Fedora 11 ? Or another Linux ?
I wouldn't expect the old 2.6.9 to compile on Fedora 11
with the default compiler.
May be use the 'compat-gcc34' , if you think that will be OK,
and use : make CC=gcc34
You may have to edit some config scripts ( Makefile's ? )
They are often hard coded with CC=gcc .
"Real time" has for long time been included in later kernels.
Real time support in current 2.6 :
