Follow-up Comment #2, bug #34608 (project make):
Thanks for these details. Let me propose
#define INTEGER_TYPE_SIGNED(t) !((t) -1 > 0)
for a warning-less replacement then. Like it?
Please re-open the bug for me, as I lack permissions to.
I used the program below with
# gcc -Wall -Wextra main.c && ./a.out
as a test:
================================================================
#include <stdio.h>
#define INTEGER_TYPE_SIGNED(t) !((t) -1 > 0)
int main() {
printf("signed %dn", INTEGER_TYPE_SIGNED(unsigned char));
printf("signed %dn", INTEGER_TYPE_SIGNED(signed char));
printf("signed %dn", INTEGER_TYPE_SIGNED(char));
return 0;
}
================================================================
