commit 0b1a949b7c1ce09136d3e4098b68a733d7bb32e2
Author: Gaetan Nadon <memsize at videotron.ca>
Date:   Thu Sep 2 19:45:54 2010 -0400

    config: use AC_CHECK_FUNCS for mkstemp, getifaddrs and getspnam
    
    Using AC_CHECK_FUNCS defines HAVE_xxx macro in config.h following
    a consistent naming convention.

    config: use AC_CHECK_FUNCS for setusercontext
    
    AC_CHECK_FUNCS defines HAVE_SETUSERCONTEXT
    
    The replaced code made an incorrect assumption that it was only
    availble on BSD-like systems.

commit d9ab9445d1c52174788fc5df34e5379747623410
Author: Gaetan Nadon <memsize at videotron.ca>

    config: add "Check for system library functions"
    
    Relocate the existing AC_CHECK_FUNCS statement.
    
    The functions are checked after the libraries checks to benefit
    from the $LIBS updated values.

commit 28d6283c5bfa9a7d19635b95de26907987799e2b
Author: Gaetan Nadon <memsize at videotron.ca>
Date:   Wed Oct 20 15:35:51 2010 -0400

    config: relocate headers, typedefs, and compiler characteristics
    
    Those checks are next following the "Check for system libraries" section.
    They are done before xorg specific configuration.

commit 849a74c4146d1f1cb961026be2540b4a9970fa26
Author: Gaetan Nadon <memsize at videotron.ca>
Date:   Tue Sep 7 16:08:06 2010 -0400

    config: add "Check for system libraries" section
    
    This section gathers all the system libraries needed for
    xdm features. They may be in standard C library on some
    platforms and in discrete libraries on others.
    
    Any xorg library is excluded from this section.
    XTRANS macros will be invoked at a later time and contribute
    additional libraries.
    
    Although a function is used to search for the library, this
    should not be confused with function checking (AC_CHECK_FUNC).
    
    Sample configuration output on GNU/Linux:
    checking for library containing getifaddrs... none required
    checking for library containing getspnam... none required
    checking for library containing setproctitle... no
    checking for library containing setusercontext... no
    checking for library containing arc4random... -lbsd
    checking for library containing crypt... -lcrypt
    
    In the Makefile, libs are pre-pended:
    LIBS = -lcrypt -lbsd
