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

Target Milestone: ---
At least on netbsd:

#include <sys/time.h>
int main() { return 0; }
> /usr/pkg/gcc8snapshot/bin/gcc -ffreestanding -Wsystem-headers test.c

# 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
