It seems as if gcc-3.3 has some builtin "stuff" which causes wrong
reports on shadowed declarations. These are the warnings caused by a
build of the current proftpd cvs tree:
---
main.c: In function `session_exit':
main.c:382: warning: declaration of `log' shadows a global declaration
<built-in>:0: warning: shadowed declaration is here
log.c:380: warning: shadowing built-in function `log'
mod_log.c: In function `find_extendedlogs':
mod_log.c:979: warning: declaration of `logf' shadows a global declaration
<built-in>:0: warning: shadowed declaration is here
---
Here is a code sippet from main.c:
---
void session_exit(int pri, void *lv, int exitval, void *dummy) {
char *log = (char *) lv;
log_pri(pri, "%s", log);
if (is_standalone && is_master) {
log_pri(PR_LOG_NOTICE, "ProFTPD " PROFTPD_VERSION_TEXT
" standalone mode SHUTDOWN");
PRIVS_ROOT
pr_delete_scoreboard();
if (!nodaemon)
unlink(PidPath);
PRIVS_RELINQUISH
}
end_login(exitval);
}
---
These warnings didn't happen with gcc-2.95.4 and gcc-3.2.
