@@ -12,6 +12,10 @@ The values of @code{LDBL_*} macros are incorrect on some platforms:
 On OpenBSD 4.0, MirBSD 10, and BeOS, they are the same as the values of the
 @code{DBL_*} macros, although @samp{long double} is a larger type than
 @samp{double}.
+On FreeBSD/x86 6.4, they represent the incorrect 53-bit precision assumptions
+in the compiler, not the real 64-bit precision at runtime.
+On AIX 7.1 with GCC 4.2 and on IRIX 6.5, they don't reflect the
+``double double'' representation of @code{long double} correctly.
