Getting "char" from INTEGER_TYPE node

[Brendon Costa <bcosta at avdat dot com dot au>]

I am having some trouble with getting type names as declared by the user 
in source. In particular if i have two functions:

void Function(int i);
void Function(char c);

when processing the parameters i get an INTEGER_TYPE node in the 
parameter list for both function as expected, however 
IDENTIFIER_POINTER(DECL_NAME(TYPE_NAME(node))) returns the string "int" 
for both nodes. I would have expected one to be "int" and the other to 
be "char". Looking at the TYPE_PRECISION for these nodes i get correct 
values though, i.e. one is 8 bit precision, the other is 32 bit.

How can i get the "char" string when a user uses char types instead of 
"int" strings?

Thanks,
Brendon.
