Gareth, XFC wont compile with gcc 3.3.5 because there was a bug in 
stl_construct.h that was fixed in gcc 3.4.0. Two choices, use gcc 3.4.x, 
or easier still if you have root access, in your file 
</usr/include/c++/3.3/bits/stl_construct.h> at line 78 insert a scope 
resolution operator in front of operator new so that it reads:

::new(static_cast<void*>(__p)) _T1(__value);

instead of:

new(static_cast<void*>(__p)) _T1(__value);

and XFC will compile.

Jeff.
