newcomer question about 64Bit version on hpux

[Thomas Porschberg]

Actually I have run gcc3.1 32Bit version on a HPUX11 machine.

Reading specs from /opt/gcc/gcc-3.1/lib/gcc-lib/hppa2.0w-hp-hpux11.00/3.1/specs
Configured with: gcc-3.1/configure --enable-languages=c,c++ --prefix=/opt/gcc/gcc-3.1 
--disable-threads : (reconfigured) gcc-3.1/configure 
--enable-languages=c,c++ --prefix=/opt/gcc/gcc-3.1 
--disable-threads --with-gnu-as --with-as=/opt/binutils/bin/as
Thread model: single
gcc version 3.1

However the kernel support 64Bit and I read about successful install 
of gcc3.1 for this plattform.

But before I jump into the 64Bit water, I have some general questions:
1) What are the advantages besides more addressroom ?
2) What are the consequences of more addressroom ?
3) Is it general to recommend to use the 64Bit version of gcc on HPUX ?
