51 OpenBSD 4.0, HP-UX 11.11, IRIX 6.5, OSF/1 5.1, mingw.
54 This function parses @samp{NaN(@var{n-char-sequence})}, but returns
55 the wrong end pointer on some platforms:
59 This function fails to parse C99 hexadecimal floating point on some
61 NetBSD 5.0, OpenBSD 4.0, AIX 5.1, HP-UX 11.11, IRIX 6.5, OSF/1 5.1,
62 Solaris 11 2010-11, mingw.

75 glibc 2.7, Cygwin 1.5.x, mingw.
78 This function cannot distinguish between ``nan'' and ``-nan'' on some
80 glibc 2.7, IRIX 6.5, OSF/1 5.1, mingw.
83 This function fails to correctly parse very long strings on some
85 MacOS X 10.5, FreeBSD 6.2, NetBSD 5.0, OpenBSD 4.0, IRIX 6.5, OSF/1 5.1, Cygwin, mingw.
88 The replacement function does not always return correctly rounded results.
