                        [this package]) to adapt to many kinds of systems.

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

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 binaries in \`/usr/local/sbin',
the config file in \`/etc', manpage in \`/usr/local/share/man', and state
data in \`/var/lib/INSTALL_NAME' (FSH layout).  You can specify other
FSH compliant layouts with \`--prefix=OPT' or \`--prefix=USR', or you
can specify a directory with \`--prefix=DIR' to install in \`DIR/sbin',
\`DIR/etc', etc.

For better control, use the options below.

Fine tuning of the installation directories:
  --sbindir=DIR          system admin executables [EPREFIX/sbin]
  --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
  --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
  --mandir=DIR           man documentation [PREFIX/man]

For even finer tuning, paths can be specified for individual files (see below)

dnl Useful macros for autoconf to check for ssp-patched gcc
dnl 1.0 - September 2003 - Tiago Sousa <mirage@kaotik.org>
dnl 1.1 - August 2006 - Ted Percival <ted@midg3t.net>
dnl     * Stricter language checking (C or C++)
dnl     * Adds GCC_STACK_PROTECT_LIB to add -lssp to LDFLAGS as necessary
dnl     * Caches all results
dnl     * Uses macros to ensure correct ouput in quiet/silent mode
dnl 1.2 - April 2007 - Ted Percival <ted@midg3t.net>
dnl     * Added GCC_STACK_PROTECTOR macro for simpler (one-line) invocation
dnl     * GCC_STACK_PROTECT_LIB now adds -lssp to LIBS rather than LDFLAGS
dnl
dnl About ssp:
dnl GCC extension for protecting applications from stack-smashing attacks
dnl http://www.research.ibm.com/trl/projects/security/ssp/
dnl
dnl Usage:
dnl Most people will simply call GCC_STACK_PROTECTOR.
dnl If you only use one of C or C++, you can save time by only calling the
dnl macro appropriate for that language. In that case you should also call
dnl GCC_STACK_PROTECT_LIB first.
dnl
dnl GCC_STACK_PROTECTOR
dnl Tries to turn on stack protection for C and C++ by calling the following
dnl three macros with the right languages.
dnl
dnl GCC_STACK_PROTECT_CC
dnl checks -fstack-protector with the C compiler, if it exists then updates
dnl CFLAGS and defines ENABLE_SSP_CC
dnl
dnl GCC_STACK_PROTECT_CXX
dnl checks -fstack-protector with the C++ compiler, if it exists then updates
dnl CXXFLAGS and defines ENABLE_SSP_CXX
dnl
dnl GCC_STACK_PROTECT_LIB
dnl adds -lssp to LIBS if it is available
dnl ssp is usually provided as part of libc, but was previously a separate lib
dnl It does not hurt to add -lssp even if libc provides SSP - in that case
dnl libssp will simply be ignored.

#
# SYNOPSIS
#
#   ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
#   This macro figures out how to build C programs using POSIX threads.
#   It sets the PTHREAD_LIBS output variable to the threads library and
#   linker flags, and the PTHREAD_CFLAGS output variable to any special
#   C compiler flags that are needed. (The user can also force certain
#   compiler flags/libs to be tested by setting these environment
#   variables.)
#
#   Also sets PTHREAD_CC to any special C compiler that is needed for
#   multi-threaded programs (defaults to the value of CC otherwise).
#   (This is necessary on AIX to use the special cc_r compiler alias.)
#
#   NOTE: You are assumed to not only compile your program with these
#   flags, but also link it with them as well. e.g. you should link
#   with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
#   $LIBS
#
#   If you are only building threads programs, you may wish to use
#   these variables in your default LIBS, CFLAGS, and CC:
#
#          LIBS="$PTHREAD_LIBS $LIBS"
#          CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
#          CC="$PTHREAD_CC"
#
#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
#   constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
#   ACTION-IF-FOUND is a list of shell commands to run if a threads
#   library is found, and ACTION-IF-NOT-FOUND is a list of commands to
#   run it if it is not found. If ACTION-IF-FOUND is not specified, the
#   default action will define HAVE_PTHREAD.
#
#   Please let the authors know if this macro fails on any platform, or
#   if you have any other suggestions or comments. This macro was based
#   on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/)
#   (with help from M. Frigo), as well as ac_pthread and hb_pthread
#   macros posted by Alejandro Forero Cuervo to the autoconf macro
#   repository. We are also grateful for the helpful feedback of
#   numerous users.

# -kthread: FreeBSD kernel threads (preferred to -pthread since SMP-able)
# lthread: LinuxThreads port on FreeBSD (also preferred to -pthread)
# -pthread: Linux/gcc (kernel threads), BSD/gcc (userland threads)
# -pthreads: Solaris/gcc
# -mthreads: Mingw32/gcc, Lynx/gcc
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
#      doesn't hurt to check since this sometimes defines pthreads too;
#      also defines -D_REENTRANT)
#      ... -mt is also the pthreads flag for HP/aCC
