+#
+# SYNOPSIS
+#
+# AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
+#
+# DESCRIPTION
+#
+# Check for baseline language coverage in the compiler for the C++11
+# standard; if necessary, add switches to CXXFLAGS to enable support.
+#
+# 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.
+#
+# The second argument, if specified 'mandatory' or if left unspecified,
+# indicates that baseline C++11 support is required and that the macro
+# should error out if no mode with that support is found. If specified
+# 'optional', then configuration proceeds regardless, after defining
+# HAVE_CXX11 if and only if a supporting mode is found.
