works fine. Also tested with

/**
 * build with
 * gcc -Wfatal-errors -Wall -Wextra -Wpedantic -std=c11
 */

#include <stdio.h>
#include <stdint.h>

#define BYTE_TO_BINARY_PATTERN "%c%c%c%c%c%c%c%c"
#define BYTE_TO_BINARY(byte)  \
  ((byte) & 0x80 ? '1' : '0'), \
  ((byte) & 0x40 ? '1' : '0'), \
  ((byte) & 0x20 ? '1' : '0'), \
  ((byte) & 0x10 ? '1' : '0'), \
  ((byte) & 0x08 ? '1' : '0'), \
  ((byte) & 0x04 ? '1' : '0'), \
  ((byte) & 0x02 ? '1' : '0'), \
  ((byte) & 0x01 ? '1' : '0') 

typedef enum
{
  A = (int)(1U << 31U),
} size_test;

int main(void)
{
  printf(BYTE_TO_BINARY_PATTERN " " BYTE_TO_BINARY_PATTERN " " BYTE_TO_BINARY_PATTERN " " BYTE_TO_BINARY_PATTERN "\n",
         BYTE_TO_BINARY(A >> 24), BYTE_TO_BINARY(A >> 16), BYTE_TO_BINARY(A >> 8), BYTE_TO_BINARY(A)
  );
}

Do you need a PR or do the change yourself?
Anyway, thank you very much for all your work!

Please make a PR so I can approve it sooner.

maybe we should re-open this until we find a solution
