+# SYNOPSIS
+#
+#   AX_CXX_COMPILE_STDCXX_11([ext|noext], [nostop])
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the C++11
+#   standard; if necessary, add switches to CXXFLAGS to enable support.
+#   CXX11FLAGS will also contain any necessary switches to enable support.
+#   HAVE_CXX11_COMPILER will additionally be set to yes if there is support.
+#   If the second argument is not specified, errors out if no mode that
+#   supports C++11 baseline syntax can be found. The first argument, if
+#   specified, indicates whether you insist on an extended mode
+#   (e.g. -std=gnu++11) or a strict conformance mode (e.g. -std=c++11).
+#   If neither is specified, you get whatever works, with preference for an
+#   extended mode.
