This patch originated with Paul; however, I and others modified it
significantly before it was accepted into binutils CVS.

Ah.  but this particular variable (which started life as
"data_import_dll") originated in a part of the code which was carried
unchanged from Paul's original.  So, it is correct that questions about
this should be directed to Paul...but I'll elaborate below.

It is defined in emultempl/pe.em.  From my personal "auto-import STATUS"
list:

So, it is on the agenda -- but I did not realize the problem would cause
a build failure for another platform.  So, that makes increases its 
priority...

Unfortunately, I am not sure why this "data sharing" between pe.em and
pe-dll.c is necessary, and haven't had time to dig into it yet.  Worse,
my development machine is dead and shipped back to manufacturer for
repair.  Sigh.

Paul, I asked you before ( in message "Re: [RFA] pei386 dll: auto-import
patch" at 2:03am on Aug 2 ) about this variable

Please comment; is there any way to eliminate the use of this global?
