  28 #
  29 #   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
  30 #
  31 # DESCRIPTION
  32 #
  33 #   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
  34 #   added in between.
  35 #
  36 #   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
  37 #   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
  38 #   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
  39 #   FLAG.
  40 #
  41 #   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

  98 #
  99 #   AX_CFLAGS_WARN_ALL   [(shellvar [,default, [A/NA]])]
 100 #   AX_CXXFLAGS_WARN_ALL [(shellvar [,default, [A/NA]])]
 101 #   AX_FCFLAGS_WARN_ALL  [(shellvar [,default, [A/NA]])]
 102 #
 103 # DESCRIPTION
 104 #
 105 #   Try to find a compiler option that enables most reasonable warnings.
 106 #
 107 #   For the GNU compiler it will be -Wall (and -ansi -pedantic) The result
 108 #   is added to the shellvar being CFLAGS, CXXFLAGS, or FCFLAGS by default.
 109 #
 110 #   Currently this macro knows about the GCC, Solaris, Digital Unix, AIX,
 111 #   HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
 112 #   Intel compilers.  For a given compiler, the Fortran flags are much more
 113 #   experimental than their C equivalents.
 114 #
 115 #    - $1 shell-variable-to-add-to : CFLAGS, CXXFLAGS, or FCFLAGS
 116 #    - $2 add-value-if-not-found : nothing
 117 #    - $3 action-if-found : add value to shellvariable
 118 #    - $4 action-if-not-found : nothing
 119 #
 120 #   NOTE: These macros depend on AX_APPEND_FLAG.

 311 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
 312 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
 313 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
 314 #
 315 # Of course, Automake must honor this variable whenever it calls a
 316 # tool from the auxiliary directory.  The problem is that $srcdir (and
 317 # therefore $ac_aux_dir as well) can be either absolute or relative,
 318 # depending on how configure is run.  This is pretty annoying, since
 319 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 320 # source directory, any form will work fine, but in subdirectories a
 321 # relative path needs to be adjusted first.
 322 #
 323 # $ac_aux_dir/missing
 324 #    fails when called from a subdirectory if $ac_aux_dir is relative
 325 # $top_srcdir/$ac_aux_dir/missing
 326 #    fails if $ac_aux_dir is absolute,
 327 #    fails when called from a subdirectory in a VPATH build with
 328 #          a relative $ac_aux_dir
 329 #
 330 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 331 # are both prefixed by $srcdir.  In an in-source build this is usually
 332 # harmless because $srcdir is `.', but things will broke when you
 333 # start a VPATH build or use an absolute $srcdir.
 334 #
 335 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 336 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 337 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 338 # and then we would define $MISSING as
 339 #   MISSING="\${SHELL} $am_aux_dir/missing"
 340 # This will work as long as MISSING is not called from configure, because
 341 # unfortunately $(top_srcdir) has no meaning in configure.
 342 # However there are other variables, like CC, which are often used in
 343 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 344 #
 345 # Another solution, used here, is to always expand $ac_aux_dir to an
 346 # absolute PATH.  The drawback is that using absolute paths prevent a
