Yes, now I know why. This is mainly about the name mangling stuff ! But
I heard something about how the vtable is handle too.
In the past, it was very difficult to use some object file caming from
an another compiler and try to link them your gcc's one. So, the new
stuff made in 3.0 and 3.2 is normally to handle this problem. They say
" that now they are mostly compatible with all other mangling scheme
from other compilers" and with the vtable management. Are you right
with this ?
