In theory you could have __CHAR_BIT__ different from 8 and what you care
about is that uint32_t has exactly 32 bits, so the check would need to be
  if (sizeof (uint32_t) * __CHAR_BIT__ != 32)
    return 0;

Also, for int16 targets where __UINT32_TYPE__ is supposedly unsigned long,
I think you would need to use:

  if (fake_swap32 (0x12345678UL) != 0x78567E12UL)
    __builtin_abort ();

(the C standard guarantees that unsigned long is at least 32-bit and
unsigned int at least 16-bit).

Ok with those changes.

Do you have write access, or will somebody from your coworkers commit it for
you?  Are you covered by ARM GCC Copyright assignment?
