Yes, of course you're right Stuart. It should be
#if (__GNUC__ >= 3) || (__GNUC__ == 2 && __GNUC_MINOR__ >= 96)


So, the correct full story is to manually edit ag-vic/vic/main.cpp at
line 182
from
#if __GNUC__ == 2 && __GNUC_MINOR__ >= 96
to
#if (__GNUC__ >= 3) || (__GNUC__ == 2 && __GNUC_MINOR__ >= 96)


Or copy following patch to ag-vic directory as file vic-gcc3.patch, then
run command
    patch -p0 <vic-gcc3.patch


Then build as normal.
