But you don't have config/tm-linux.h.

You should have config/tm-linux.h enclosed here and modify all the
Linux tm files to include it. Otherwise, linuxthreads won't work
right if REALTIME_HI and REALTIME_LO are not correct.

My gdb tree is a mess. I don't have the time to clean it up. I don't
want to spend time on it before gdb in CVS is in reasonable shape.
