P. S. I apologize for an accidental duplicate, it is a result of network error, I got a Bad gateway page and re-submitted the issue, however turned out it already got submitted despite the error message.

Please close as a duplicate.

Given that comment to the code explicitly state these asserts can be just removed, perhaps either remove it or at least do this:

#ifndef __ppc__
static char _ae_bool_must_be_8_bits_wide [1-2*((int)(sizeof(ae_bool))-1)*((int)(sizeof(ae_bool))-1)];

And then below:

void ae_never_call_it()
#ifndef __ppc__
