error: `.' cannot appear in a constant-expression in gcc 3.4.2 version

[anandi.thirunavukkarasu@wipro.com]

I am using a switch case statement in my code. The case condition checks
for a "class object.value".
This is throwing an error saying 

error: `.' cannot appear in a constant-expression

The same code works fine in other versions of gcc (i.e. 2.96 ). But I
encounter this problem in gcc 3.4.2 version.
Can u help me with a fix for this issue?
