8 Portability problems fixed by Gnulib:
11 The values of @code{LDBL_*} macros are incorrect on some platforms:
12 On OpenBSD 4.0, MirBSD 10, and BeOS, they are the same as the values of the
13 @code{DBL_*} macros, although @samp{long double} is a larger type than
15 On FreeBSD/x86 6.4, they represent the incorrect 53-bit precision assumptions
16 in the compiler, not the real 64-bit precision at runtime.
17 On Linux/PowerPC with GCC 4.4, on AIX 7.1 with GCC 4.2, and on IRIX 6.5,
18 they don't reflect the ``double double'' representation of @code{long double}
