Shame on me !!!
All is going well, now.
thanks Marko, CTzen.
For information, v_sql is a query, and a wrong query, and in my exception bloc, I wrote nothing so no output !!!
Sorry.
Best regards.

For those people who have the same problem, here's the response of the oracle support :
"maybe you are hitting the bug 5245451 which is fixed in 11i and there exist some backports
for different 10g version and platform but there doesn't exist for Windows 2003."
So this is a "well-known" bug...
When I try to compile and old procedure (oracle 8.1.7) with plsql developer 7 with an oracle 10g database, I reach the error :
Error: PL/SQL: ORA-00904: "FLAG" : identificateur non valide
EXPLANATION :
Before :
select flag into v_flag from my_table@my_dblink;
=> OK !!!
Now with 10g :
Error...
