problem with the gcc 3.4.4

[HASSAN AL MOATASSIME]

 Hi,
I have a problem with the compiler gcc 3.4.4.
With the gcc 3.2 compiler, i have no problem with the following instruction :
               creal(U0[i])=PartieReelle;
               cimag(U0[i])=PartieImaginaire;

Now with the gcc 3.4.4 i have the folowing message :
 

-- erreur: invalid lvalue in assignment

-- erreur: invalid lvalue in assignment

Sincerly yours.
