2 @subsection @code{getopt_long}
5 Gnulib module: getopt-gnu
7 Portability problems fixed by Gnulib:
10 The function @code{getopt_long} does not obey the combination of
11 @samp{+} and @samp{:} flags in the options string on some platforms:
14 The use of @samp{W;} in the optstring argument to does not always
15 allow @code{-W foo} to behave synonymously with @code{--foo}:
18 The function @code{getopt_long} does not support the @samp{+} flag in
19 the options string on some platforms:
20 MacOS X 10.5, AIX 5.2, OSF/1 5.1, Solaris 10.
22 The value of @code{optind} after a missing required argument is wrong
26 The function @code{getopt_long} does not obey the @samp{-} flag in the
27 options string when @env{POSIXLY_CORRECT} is set on some platforms:
30 Some implementations fail to reset state, including re-checking
31 @env{POSIXLY_CORRECT}, when @code{optind} is set to @samp{0}:
34 The function @code{getopt_long} does not support options with optional
35 arguments on some platforms:
36 MacOS X 10.5, OpenBSD 4.0, AIX 5.2, IRIX 6.5, Solaris 10, Cygwin 1.5.x.
38 This function is missing on some platforms:
39 AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Interix 3.5.
