Bug ID: 83826
Summary: Fixinclude creates redefinitions
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: coypu at sdf dot org
Target Milestone: ---
At least on netbsd:
#include <stdint.h>
#include <sys/time.h>
int main() { return 0; }
> /usr/pkg/gcc8snapshot/bin/gcc -ffreestanding -Wsystem-headers test.c

note: this is the location of the previous definition
# define INT8_MIN (-INT8_MAX - 1)
Repeating for a lot of things.
using -save-temps, it seems we have include order:
fixincludes stdint.h:
#undef WORKING_THING
#define WORKING_THING 0x7f
normal stdint.h:
#define WORKING_THING 0x7F
