[ale] c++, dynamic linking etc.

[Alan Stewart]

I thought dynamic linking was the default. My ldd output (compiling with 
g++/gcc 2.96) looks like this:

        libz.so.1 => /usr/lib/libz.so.1 (0x40031000)
        libtiff.so.3 => /usr/lib/libtiff.so.3 (0x40040000)
        libstdc++-libc6.2-2.so.3 => /usr/lib/libstdc++-libc6.2-2.so.3 
(0x40083000)
        libm.so.6 => /lib/i686/libm.so.6 (0x400c6000)
        libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
        libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x400e8000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
