           Summary: mozilla configure script thinks 3.3.1 has pedantic long
                    long bug
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: calum dot mackay at sun dot com
                CC: gcc-bugs at gcc dot gnu dot org

Whilst configuring the mozilla appsuite with 3.3.1, the following error occurs:

checking whether C++ compiler has -pedantic long long bug... yes
configure: error: Your compiler appears to have a known bug where long long is m
iscompiled when using -pedantic.  Reconfigure using --disable-pedantic. 

I can reproduce the test:

diz $ cat conftest.C 
int main () {
        if (sizeof(long long) != 8) { return 1; } 
        return 0;
}
diz $ c++ -pedantic conftest.C
conftest.C: In function `int main()':
conftest.C:2: error: ISO C++ does not support `long long'

Is mozilla using a valid test?

I'm using the Debian unstable packages:

diz $ c++ -v

Thread model: posix
gcc version 3.3.1 20030728 (Debian prerelease)

Is this possibly related to bug 11459?

There was a change in 3.3.1 which pedantic warnings into errors because those were changing 
into warnings from errors when -pedantic was added.
I think the check is invalid as it should not be checking on if -pedantic errors out when long long 
is used but check for the micompiled instead.
