On further research, I think this is wrong for GNU/Linux.  It was
probably written for other operating systems in mind.  Undefining
DATA_START on GNU/Linux is pretty harmless; as I said, this causes Emacs
to fall back on another heuristic method for determining the start of
the data segment.  (Anyway, this change only affects this particular
platform).  So, I've checked in the change.

Hi,

I compiled using GCC 4.3.2 from debian lenny (abi=32):

GNU Emacs 23.0.91.1 (mips64el-unknown-linux-gnu, X toolkit) of
2009-03-15 on gcc51   

When launching emacs (in text mode) I get a *Warnings* window
with the following message:

Emergency (alloc): Warning: past 85% of memory limit

The machine gcc51 has 1GB of RAM so this warning seems surprising.

Sincerely,

Laurent
