g++ 4.0 error: expected nested-name-specifier

[Coumou Dim]

I get the following error when using g++ 4.0.2:

g++ -c -pipe -O2 -fmessage-length=0 -Wall -D_FORTIFY_SOURCE=2 -g -DUSE_LIB64_PATHES -w -O2 -fmessage-length=0 -Wall -D_FORTIFY_SOURCE=2 -g -DUSE_LIB64_PATHES   -I/usr/lib/qt3/mkspecs/default -I. -I../applied_math -I../computational_geometry -I../finite_elements -I../interfaces -I../pde_operators -I../solver -I../generic_finite_volumes -I../main_library -I../two_phase_flow -I../interrelations -I/usr/include -I/usr/X11R6/include -o obj/LinearDiffusionAlgorithm.o LinearDiffusionAlgorithm.cpp
LinearDiffusionAlgorithm.h:66: error: expected nested-name-specifier
LinearDiffusionAlgorithm.h:66: error: expected ‘;’ before ‘*’ token

This piece of code looks as follows:

template<typename fT,stl_index dim>
class LinearDiffusionAlgorithm {

typename A<fT,dim>*  B; // this is line 66

};

This compiles fine using Intel c++ 8.0 compiler but not with g++ 4.0. Can anybody give me a hint of what is going wrong?
Many thanks in advance,

cheers,
