++# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
++# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
++# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
++#
++# Of course, Automake must honor this variable whenever it calls a
++# tool from the auxiliary directory. The problem is that $srcdir (and
++# therefore $ac_aux_dir as well) can be either absolute or relative,
++# depending on how configure is run. This is pretty annoying, since
++# it makes $ac_aux_dir quite unusable in subdirectories: in the top
++# source directory, any form will work fine, but in subdirectories a
++# relative path needs to be adjusted first.
++#
++# $ac_aux_dir/missing
++# fails when called from a subdirectory if $ac_aux_dir is relative
++# $top_srcdir/$ac_aux_dir/missing
++# fails if $ac_aux_dir is absolute,
++# fails when called from a subdirectory in a VPATH build with
++# a relative $ac_aux_dir
++#
++# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
++# are both prefixed by $srcdir. In an in-source build this is usually
++# harmless because $srcdir is `.', but things will broke when you
++# start a VPATH build or use an absolute $srcdir.
++#
++# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
++# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
++# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
++# and then we would define $MISSING as
++# MISSING="\${SHELL} $am_aux_dir/missing"
++# This will work as long as MISSING is not called from configure, because
++# unfortunately $(top_srcdir) has no meaning in configure.
++# However there are other variables, like CC, which are often used in
++# configure, and could therefore not use this "fixed" $ac_aux_dir.
++#
++# Another solution, used here, is to always expand $ac_aux_dir to an
++# absolute PATH. The drawback is that using absolute paths prevent a
++# configured tree to be moved without reconfiguration.

++# is unlikely to handle the host's binaries.

++Usage: $0 [OPTION]... [VAR=VALUE]...
++
++To assign environment variables (e.g., CC, CFLAGS...), specify them as
++VAR=VALUE. See below for descriptions of some of the useful variables.
++
++Defaults for the options are specified in brackets.
++
++Configuration:
++ -h, --help display this help and exit
++ --help=short display options specific to this package
++ --help=recursive display the short help of all the included packages
++ -V, --version display version information and exit
++ -q, --quiet, --silent do not print \`checking ...' messages
++ --cache-file=FILE cache test results in FILE [disabled]
++ -C, --config-cache alias for \`--cache-file=config.cache'
++ -n, --no-create do not create output files
++ --srcdir=DIR find the sources in DIR [configure dir or \`..']
++
++Installation directories:
++ --prefix=PREFIX install architecture-independent files in PREFIX
++ [$ac_default_prefix]
++ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
++ [PREFIX]
++
++By default, \`make install' will install all the files in
++\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
++an installation prefix other than \`$ac_default_prefix' using \`--prefix',
++for instance \`--prefix=\$HOME'.
++
++For better control, use the options below.
++
++Fine tuning of the installation directories:
++ --bindir=DIR user executables [EPREFIX/bin]
++ --sbindir=DIR system admin executables [EPREFIX/sbin]
++ --libexecdir=DIR program executables [EPREFIX/libexec]
++ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
++ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
++ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
++ --libdir=DIR object code libraries [EPREFIX/lib]

++
++INDEX
++ psignal
++
++ANSI_SYNOPSIS
++ #include <stdio.h>
++ void psignal(int <[signal]>, const char *<[prefix]>);
++
++TRAD_SYNOPSIS
++ #include <stdio.h>
++ void psignal(<[signal]>, <[prefix]>)
++ int <[signal]>;
++ const char *<[prefix]>;
++
++DESCRIPTION
++Use <<psignal>> to print (on standard error) a signal message
++corresponding to the value of the signal number <[signal]>.
++Unless you use <<NULL>> as the value of the argument <[prefix]>, the
++signal message will begin with the string at <[prefix]>, followed by a
++colon and a space (<<: >>). The remainder of the signal message is one
++of the strings described for <<strsignal>>.
++
++RETURNS
++<<psignal>> returns no result.
++
++PORTABILITY
++POSIX.1-2008 requires <<psignal>>, but the strings issued vary from one
++implementation to another.
++
++Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
++<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

+ DESCRIPTION
+ <<strerror_r>> converts the error number <[errnum]> into a
+ string and copies the result into the supplied <[buffer]> for
+-a length up to <[n]>, including the NUL terminator. The value of
+-<[errnum]> is usually a copy of <<errno>>. If <<errnum>> is not a known
++a length up to <[n]>, including the NUL terminator. The value of
++<[errnum]> is usually a copy of <<errno>>. If <<errnum>> is not a known
+ error number, the result is the empty string.
+
+ See <<strerror>> for how strings are mapped to <<errnum>>.
+
+ RETURNS
+-This function returns a pointer to a string. Your application must
+-not modify that string.
++There are two variants: the GNU version always returns a NUL-terminated
++string, which is <[buffer]> if all went well, but which is another
++pointer if <[n]> was too small (leaving <[buffer]> untouched). If the
++return is not <[buffer]>, your application must not modify that string.
++The POSIX version returns 0 on success, <[EINVAL]> if <<errnum>> was not
++recognized, and <[ERANGE]> if <[n]> was too small. The variant chosen
++depends on macros that you define before inclusion of <<string.h>>.
+
+ PORTABILITY
+-<<strerror_r>> is a GNU extension.
++<<strerror_r>> with a <[char *]> result is a GNU extension.
++<<strerror_r>> with an <[int]> result is required by POSIX 2001.
++This function is compliant only if <<_user_strerror>> is not provided,
++or if it is thread-safe and does not modify <<errno>>.
++
++POSIX states that the contents of <[buf]> are unspecified on error,
++although this implementation guarantees a NUL-terminated string for
++all except <[n]> of 0.
++
++POSIX recommends that unknown <[errnum]> result in a message including
++that value, however it is not a requirement and this implementation
++provides only an empty string (unless you provide <<_user_strerror>>).
++POSIX also recommends that unknown <[errnum]> fail with EINVAL even
++when providing such a message, however it is not a requirement and
++this implementation will return success if <<_user_strerror>> provided
++a non-empty alternate string.
+
+ <<strerror_r>> requires no supporting OS subroutines.
