Looking at the history:

Index: real.h

 #define SIGNIFICAND_BITS       (128 + HOST_BITS_PER_LONG)
-#define EXP_BITS               (32 - 5)
+#define EXP_BITS               (32 - 6)
 #define MAX_EXP                        ((1 << (EXP_BITS - 1)) - 1)
[...]

but real.c wasn't updated: it still has

   denormal number fits in 17 exponent bits; we store 27.

that comes from r83133.
