Maybe there are similar issues elsewhere, but this one happened
to bother me... This warning is also issed by GCC 3.3, so I guess
it is not a regression. But it's a silly warning after errors.
=================== t.c ===================
int bar (void);
int foo (void)
{
int i;
int i;
i = bar ();
return 2*i;
}
===========================================
$ gcc -Wall -Wextra -O2 t.c
t.c: In function 'foo':
t.c:5: error: redeclaration of 'i' with no linkage
t.c:4: error: previous declaration of 'i' was here
t.c:4: warning: unused variable 'i'
