 12.2 Autoconf Macros
 ====================
 
 The macro names all begin with "GUILE_".
 
  -- Autoconf Macro: GUILE_PROGS
      This macro looks for programs `guile', `guile-config' and
      `guile-tools', and sets variables GUILE, GUILE_CONFIG and
      GUILE_TOOLS, to their paths, respectively.  If either of the first
      two is not found, signal error.
 
      The variables are marked for substitution, as by `AC_SUBST'.
 
 
  -- Autoconf Macro: GUILE_FLAGS
      This macro runs the `guile-config' script, installed with Guile, to
      find out where Guile's header files and libraries are installed.
      It sets two variables, GUILE_CFLAGS and GUILE_LDFLAGS.
 
      GUILE_CFLAGS: flags to pass to a C or C++ compiler to build code
      that uses Guile header files.  This is almost always just a `-I'
      flag.
 
      GUILE_LDFLAGS: flags to pass to the linker to link a program
      against Guile.  This includes `-lguile' for the Guile library
      itself, any libraries that Guile itself requires (like
      -lqthreads), and so on.  It may also include a `-L' flag to tell
      the compiler where to find the libraries.
 
      The variables are marked for substitution, as by `AC_SUBST'.
 
 
  -- Autoconf Macro: GUILE_SITE_DIR
      This looks for Guile's "site" directory, usually something like
      PREFIX/share/guile/site, and sets var GUILE_SITE to the path.
      Note that the var name is different from the macro name.
 
      The variable is marked for substitution, as by `AC_SUBST'.
 
 
  -- Autoconf Macro: GUILE_CHECK_RETVAL var check
      VAR is a shell variable name to be set to the return value.  CHECK
      is a Guile Scheme expression, evaluated with "$GUILE -c", and
      returning either 0 or non-#f to indicate the check passed.
      Non-0 number or #f indicates failure.     Avoid using the
      character "#" since that confuses autoconf.
 
 
  -- Autoconf Macro: GUILE_MODULE_CHECK var module featuretest
           description
      VAR is a shell variable name to be set to "yes" or "no".  MODULE
      is a list of symbols, like: (ice-9 common-list).  FEATURETEST is
      an expression acceptable to GUILE_CHECK, q.v.  DESCRIPTION is a
      present-tense verb phrase (passed to AC_MSG_CHECKING).
 
 
  -- Autoconf Macro: GUILE_MODULE_AVAILABLE var module
      VAR is a shell variable name to be set to "yes" or "no".  MODULE
      is a list of symbols, like: (ice-9 common-list).
 
 
  -- Autoconf Macro: GUILE_MODULE_REQUIRED symlist
      SYMLIST is a list of symbols, WITHOUT surrounding parens, like:
      ice-9 common-list.
 
 
  -- Autoconf Macro: GUILE_MODULE_EXPORTS var module modvar
      VAR is a shell variable to be set to "yes" or "no".  MODULE is a
      list of symbols, like: (ice-9 common-list).  MODVAR is the Guile
      Scheme variable to check.
 
 
  -- Autoconf Macro: GUILE_MODULE_REQUIRED_EXPORT module modvar
      MODULE is a list of symbols, like: (ice-9 common-list).  MODVAR is
      the Guile Scheme variable to check.
