+# SYNOPSIS
+#
+#   AX_TLS([action-if-found], [action-if-not-found])
+#
+# DESCRIPTION
+#
+#   Provides a test for the compiler support of thread local storage (TLS)
+#   extensions. Defines TLS if it is found. Currently knows about GCC/ICC
+#   and MSVC. I think SunPro uses the same as GCC, and Borland apparently
+#   supports either.
