Hi, 
I have a problem: inconsistent treetment of cast expressions.

Here is the program p1.c: 

int * int_ptr;
short * short_ptr;
char * char_ptr;

f1()
{
    ((char *)(int_ptr)) += 4;
    ((char *)(short_ptr)) += 4;
    ((char *)(char_ptr)) += 4;
}

gcc -pedantic p1.c

p1.c: In function `f1':
p1.c:7: warning: ANSI C forbids use of cast expressions as lvalues
p1.c:8: warning: ANSI C forbids use of cast expressions as lvalues
p1.c:9: invalid lvalue in assigmnet

In the first two cases a warning is issued, and the last case causes an error.
I'm using gcc 2.7.2.
What do you think?
