27# SYNOPSIS
28#
29#   AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
30#
31# DESCRIPTION
32#
33#   Check for baseline language coverage in the compiler for the C++11
34#   standard; if necessary, add switches to CXXFLAGS to enable support.
35#
36#   The first argument, if specified, indicates whether you insist on an
37#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
38#   -std=c++11).  If neither is specified, you get whatever works, with
39#   preference for an extended mode.
40#
41#   The second argument, if specified 'mandatory' or if left unspecified,
42#   indicates that baseline C++11 support is required and that the macro
43#   should error out if no mode with that support is found.  If specified
44#   'optional', then configuration proceeds regardless, after defining
45#   HAVE_CXX11 if and only if a supporting mode is found.

201# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
202# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
203# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
204#
205# Of course, Automake must honor this variable whenever it calls a
206# tool from the auxiliary directory.  The problem is that $srcdir (and
207# therefore $ac_aux_dir as well) can be either absolute or relative,
208# depending on how configure is run.  This is pretty annoying, since
209# it makes $ac_aux_dir quite unusable in subdirectories: in the top
210# source directory, any form will work fine, but in subdirectories a
211# relative path needs to be adjusted first.
212#
213# $ac_aux_dir/missing
214#    fails when called from a subdirectory if $ac_aux_dir is relative
215# $top_srcdir/$ac_aux_dir/missing
216#    fails if $ac_aux_dir is absolute,
217#    fails when called from a subdirectory in a VPATH build with
218#          a relative $ac_aux_dir
219#
220# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
221# are both prefixed by $srcdir.  In an in-source build this is usually
222# harmless because $srcdir is '.', but things will broke when you
223# start a VPATH build or use an absolute $srcdir.
224#
225# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
226# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
227#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
228# and then we would define $MISSING as
229#   MISSING="\${SHELL} $am_aux_dir/missing"
230# This will work as long as MISSING is not called from configure, because
231# unfortunately $(top_srcdir) has no meaning in configure.
232# However there are other variables, like CC, which are often used in
233# configure, and could therefore not use this "fixed" $ac_aux_dir.
234#
235# Another solution, used here, is to always expand $ac_aux_dir to an
236# absolute PATH.  The drawback is that using absolute paths prevent a
237# configured tree to be moved without reconfiguration.
