I do not really understand the problem, since I do not deal with
platforms needing a non-null value for that symbol.

However, I do use the symbol itself to determine which entry points
should be exported from the "dll" on the OS400:

------- packages/OS400/make-lib.sh
# Gather the list of symbols to export.

EXPORTS=`grep '^CURL_EXTERN[ ]'
\
              "${TOPDIR}"/include/curl/*.h
\
              "${SCRIPTDIR}/ccsidcurl.h"
|
         sed -e 's/^.*CURL_EXTERN[ ]\(.*\)(.*$/\1/'
\
             -e 's/[ ]*$//'
\
             -e 's/^.*[ ][ ]*//'
\
             -e 's/^\*//'
\
             -e 's/(\(.*\))/\1/'`
-------

As a consequence, I don't care about the CURL_EXTERN definition, but I
do care about its use. Thus... Don't remove or replace it in the
declarations. Thanks.

Cheers,
Patrick
