I think there is some new problem.

Downloading cvs-trunk with -D "20080730 17:14" bootstraps and works 
without warning.

Instead -D "20080730 17:15" fails to bootstrap, but it is solved with 
the patch discussed here [1] or using systty.h from "20080730 17:14".

After solving the bootstrap problem the warning shows up.

Below [2] there are the differences between "20080730 17:14" and 
"20080730 17:15" and it seem hard to think that the patch is the cause 
of the warning.

Perhaps the new handling (in 20080730 17:15) of getrlimit?

Cheers,
   Angelo.
