9 Portability problems fixed by Gnulib:
12 This function does not support size specifiers as in C99 (@code{hh}, @code{ll},
13 @code{j}, @code{t}, @code{z}) on some platforms:
14 AIX 5.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 9, Cygwin 2006, mingw, BeOS.
16 printf of @samp{long double} numbers is unsupported on some platforms:
19 printf @code{"%f"}, @code{"%e"}, @code{"%g"} of Infinity and NaN yields an
20 incorrect result on some platforms:
21 AIX 5.2, OSF/1 5.1, Solaris 10, mingw.
23 This function does not support the @samp{a} and @samp{A} directives on some
25 glibc-2.3.6, MacOS X 10.3, NetBSD 3.0, OpenBSD 4.0, AIX 5.2, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin, mingw, BeOS.
27 This function does not support the @samp{F} directive on some platforms:
28 NetBSD 3.0, AIX 5.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 9, Cygwin, mingw, BeOS.
30 This function does not support format directives that access arguments in an
31 arbitrary order, such as @code{"%2$s"}, on some platforms:
32 NetBSD 3.0, mingw, BeOS.
34 This function doesn't support the @code{'} flag on some platforms:
35 NetBSD 3.0, Cygwin 2006, mingw.
37 This function behaves incorrectly when a @samp{-} flag and a negative width
38 are specified together, on some platforms:
41 printf @code{"%010f"} of NaN and Infinity yields an incorrect result (padded
42 with zeroes) on some platforms:
43 MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0, AIX 5.2, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 2007, mingw.
45 This function does not support precisions larger than 512 or 1024 in integer,
46 floating-point and pointer output on some platforms:
49 This function can crash in out-of-memory conditions on some platforms:
50 MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0.
