Actually the only specific problem that this currently causes is that a
spurious -DNEED_sys_nerr and -DNEED_sys_errlist are generated, (or
whatever the macros are that trigger building the two I'm not running
configure right now :), which means that programs that link with
libiberty will get different static versions of sys_nerr, and
sys_errlist.

The reason I brought this up is so that the people who do core
development would be aware of the problems associated with using/not
using the DATA keyword in .def files.  and the consequences to configure
scripts.

I don't know who is responsible for maintaining the autoconf scripts
(Ian?) but I would think that probably not breaking configure (on 200+
targets :) is more important than the occasional breakage from programs
not including the correct header.  so I would vote to not use the DATA
keyword in cygwin32.

Then again this isn't a democracy.
