not really convenient. For example:

int foo(void)
{
        int tmp;

        tmp = bar();
        [...]
        return tmp;
}

How do you know if tmp store an errno value ? You have to look into bar and  so
on...By using "enum errnoval", gdb can directly tell you that a variable stores
an errno value.

Thanks
