[Bug middle-end/14088] New: Hexfloat constants with uppercase 0X prefix fail

[dannysmith at gcc dot gnu dot org]

Uppercase 0X as heaxadecimal prefix to hex float consts cause value to be 
interpreted as  0

This fails: 

#define x1   (double)0x1p1
#define x2   (double)0X1p1

char tst[(x1 == x2) ?  1 : -1];

Correct: 
-------------------- 
#include <stdio.h> 
 
#define x1   (double)0x1p1 
#define x2   (double)0X1p1 
 
int main () 
{ 
  printf ("%f == %f", x1, x2); 
}
