[Bug web/64968] Upgrade GCC Bugzilla to 5.0

--- Comment #32 from Frédéric Buclin <LpSolit at netscape dot net> ---
For some reason, DateTime::TimeZone->new(name => 'local') sometimes returns
Asia/Kolkata, which explains the -05:30 offset observed in the famous 2% of
bugmails with an incorrect timestamp. I added extra debug code to track which
TZ method is the culprit.

I found only one user account which uses the Asia/Kolkata timezone. But no
reason why this would interact with the local timezone.

I am trying to compile with these options:

../gcc-5.1.0/configure --with-gnu-as --with-ld=/usr/ccs/bin/ld --without-gnu-ld
--enable-shared --enable-languages=c,c++,fortran,objc,obj-c++,go

My system is Solaris 10 x86-64 bits.

I am trying to compile this with GCC 4.9.2, compiled on this very same machine
and working correctly for other source code I compile.

The GMP versions apparently conflicting are 6.0.0a and 5.1.2. I was running
5.1.2 and upgraded to 6.0.0a when I got this error, with the same result.

Also occurred on CentOS 7, solved by installing gcc-c++.
