Hmm checking, but one reason may be that your compiler used a builtin. 
e.g. ceill(0.25) is optimized into ceilf(0.25) which yields a valid 
result. Do we run the math testsuite with -fno-builtin?

Please try the following:

extern long double ceill(long double x);
extern void abort(void);

int main()
{
  if ((int)ceill(0.25) != 1)
	abort();
  return 0;
}
