gcc 3 barfs in utils.c with Nagios CVS/embedded Perl.

[Stanley Hopcroft]

Dear Folks, 

>From a last 10 day CVS of 2.x, with gcc 3 on FreeBSD, Nagios fails to 
build with embedded Perl in base/utils.c.

*** Configuration summary for nagios 2.0b3 04-03-2005 ***:

 General Options:
 -------------------------
        Nagios executable:  nagios
        Nagios user/group:  nagios,nagiocmd
       Command user/group:  nagios,nagiocmd
            Embedded Perl:  yes, with caching
             Event Broker:  yes
        Install ${prefix}:  /usr/local/nagios
                Lock file:  ${prefix}/var/nagios.lock
           Init directory:  /usr/local/etc/rc.d
                  Host OS:  freebsd5.4

 Web Interface Options:
 ------------------------
                 HTML URL:  http://localhost/nagios/
                  CGI URL:  http://localhost/nagios/cgi-bin/
 Traceroute (used by WAP):  /usr/sbin/traceroute


Review the options above for accuracy.  If they look okay,
type 'make all' to compile the main program and CGIs.

Using built-in specs.
Configured with: FreeBSD/i386 system compiler
Thread model: posix
gcc version 3.4.2 [FreeBSD] 20040728
ws11114> 

I will try and understand what is causing this problem.

The same code compiles cleanly on the (old) gcc 2 that is standard on 
FreeBSD RELENG4 (ie all FreeBSD 4.x with the system compiler).

Yours sincerely.
