Consider the following C code snippet:
#include <stdio.h>
int main()
{
char x = -4;
if (x < 0)
printf("x is negative\n");
else
printf("x is positive\n");
}
If I compile it with host gcc, there is no warning and the message "x is
negative" is printed.
If I compile it with ppc_8xx-gcc there is a warning "main.c:11: warning:
comparison is always false due to limited range of data type" and the program
prints message "x is positive".
To correct the problem I have to put signed before char.
Bye,
Antonio.
